We have the graph of a function (say f(x)).
We have to determine which of the given statements are correct w.r.t this graph of f(x).
What do you mean by domain and range of a function?The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
According to the question, we have the equation of this line as -
y = -5.
The value of y is constant for every value of x. Therefore, the range of the function is Set → {- 5}.
The function has same value → y= -5 for all values of x, ranging from →
- ∞ to + ∞, Therefore, its domain is the set of all Real numbers.
A function can have same value of y for different values of x.
Hence, Option B and D are correct.

What is the Gcf of 10 and 6?
The GCF of 10 and 6 is 2. May this will help you.
Please help what is the answer
9514 1404 393
Answer:
E
Step-by-step explanation:
You can see from the first and last points that the data set demonstrates a slight upward trend. That means the slope of the regression line will be near +1, eliminating all choices except A and E.
The y-intercept of such a line will not be negative, eliminating choice A, leaving choice E as the only reasonable option.
__
If you input this data to a suitable calculator or spreadsheet, it can find the parameters of the regression line for you. (We presume you have been introduced to such tools.) My graphing calculator gave the results shown below, confirming E is the correct choice.

A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3as the weight density of water.)
(A water tank shaped like a triangular prism is given. The base of the prism is at the top and a spout is located at the top of the tank. The dimensions of the tank are 9 meters long, 4 meters wide, and 4 meters deep. The spout is 3 meters long.)
Answer:
W = 1.06 MJ
Step-by-step explanation:
- We will use differential calculus to solve this problem.
- Make a differential volume of water in the tank with thickness dx. We see as we traverse up or down the differential volume of water the side length is always constant, hence, its always 8.
- As for the width of the part w we see that it varies as we move up and down the differential element. We will draw a rectangle whose base axis is x and vertical axis is y. we will find the equation of the slant line that comes out to be y = 0.5*x. And the width spans towards both of the sides its going to be 2*y = x.

Hey there!
25: 1, 5, & 25
because: 5 * 5 = 25 & 1 * 25 = 25
45: 1, 3, 5, 9, 15, 45
because: 1 * 45 = 45, 3 * 15 = 45, & 5 * 9 = 45
Common factors: 1 & 5
The bigger number of those two is 5
Therefore, your possible answer is: 5

If AB= x+4, BC=2x-10, and AC=2x+1, then find the value for x
Answer:
[tex] \boxed{x = 7} [/tex]
Step-by-step explanation:
Given:
AB = x + 4BC = 2x – 10AC = 2x + 1We can illustrate this relationship as:
(2x + 1)
___↑___
| |
A — B — C
|____|___|
↓ ↓
(x + 4) (2x – 10)
_______________________________
When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.
Thus:
(x + 4) + (2x – 10) = (2x + 1)
[Regroup terms]
(x + 2x) + (4 – 10) = (2x + 1)
[Simplify]
(3x – 6) = (2x + 1)
[subtract 2x from both sides to isolate the variable]
(3x – 6) – 2x = (2x + 1) – 2x
[Regroup terms]
(3x – 2x) – 6 = (2x – 2x) + 1
x – 6 = 1
[Add 6 to both sides to isolate the constant]
x – 6 + 6 = 1 + 6
[Simplify]

If mean of first 3 digits is 19 and next 2 digits is 18, what would be the mean of all 5 digits?
Mean of total 5 digits is 18.6
Given:
Mean of first 3 digit = 19
Mean of next 2 digit = 18
Find:
Mean of total 5 digits
Computation:
Sum of first 3 digit = Mean of first 3 digit × Number of digits
Sum of first 3 digit = 19 × 3
Sum of first 3 digit = 57
Sum of next 2 digit = Mean of first 3 digit × Number of digits
Sum of next 2 digit = 18 × 2
Sum of next 2 digit = 36
Total of 5 digit = Sum of first 3 digit + Sum of next 2 digit
Total of 5 digit = 57 + 36
Total of 5 digit = 93
Mean of total 5 digits = Total of 5 digit / 5
Mean of total 5 digits = 93 / 5
Mean of total 5 digits = 18.6

The answer is "mean of all 5 digits is 18.6" and the further calculation can be defined as follows:
The mean would be the total number divided by the number of numbers. To obtain the mean, we add all the numbers and divide by number.It is also known as the "average" value, which was established by summing all data points then divided by the information gain amount.Its most popular statistics used to measure the center of a collection of data and analysis are the statistics sometimes referred to it as average by statistics.In this question, let the value are a,b,c..., and e So,Mean of 3 digits:

Complete the arithmetic sequence with its missing terms, then state the rate of change for the sequence.
92, _, _, _, 80
Answer:
89,86,83
Step-by-step explanation:
92-80=12
12÷4=3
80+3=83
83+3=86
86+3=89
The complete arithmetic sequence will be: 92, 89, 86, 83, and 80.
What is an arithmetic sequence?Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as;
aₙ = a₁ + (n - 1)d
Given; The first term (a₁) is 92 and the fifth term (a₅) is 80.
Then the common difference between the terms will be given as;
a₅ = a₁ + (5 - 1)d
80 = 92 + 4d
-12 = 4d
d = -3
Then the missing terms will be
92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12
92, 89, 86, 83, and 80
Hence, the complete arithmetic sequence will be: 92, 89, 86, 83, and 80.

Which equation corresponds to the following word problem?
Cory spends $6.50 on snacks at a gas station. He also buys gas, which costs $2.78 per gallon. If he spends a total of $24.00 at the gas station, how many
gallons of gas did he buy? Let g equal the number of gallons of gas.
(1 point)
O 6.509 +2.78 = 24.00
O 2.789 -6.50 = 24.00
O 6.50g - 2.78 = 24.00
2.789 +6.50 = 24.00
Answer:
Cory bought 6.30 gallons of gas at the gas station.
Step-by-step explanation:
total amount = cost of snacks + amount spent on gas
[tex]$\$ 24.00=\$ 6.50+\$ 2.78 \mathrm{~g}$[/tex]

Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]

To identify the true statement, I will make use of graphical method.
See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]
From the attached graph, we can see that the graph as a minimum at:
[tex](x,y) = (2,-8)[/tex]
And it opens upward.
This implies that the minimum y-value of f(x) is at -8, and it has no maximum.
In other words, the range of the function is:

Hence, the true statement is option (a):
