How do you do this, because I really do not know how to do this and plz explain how to do this
Answer:
A
Step-by-step explanation:
the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5
so the answer should be
-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity
when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.
for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)

To find the formula of the binomial in the form (a + b)2, we will just multiply (a + b) (a + b).
Answer:
a^2b^3
Step-by-step explanation:
Expression:
ab^2(ab)

A $270 suit is marked down by 30%. Find the sale price . PLZ HELP IM NOT GOOD WITH PECENTGE .
Answer:
189$
Step-by-step explanation:
30% of 270 = 81
270-81=189
Answer:
The sale price is $189.
Step-by-step explanation:
Rule:
To find the percent of a number, change the percent to a decimal by moving the decimal point of the percent two places left. Then multiply it by the number.
Example:
Find 20% of 200.
Change the percent, 20, to a decimal by moving the decimal point of 20 two places left.
20% = 0.20
Now multiply 0.20 by 200.
0.20 × 200 = 40
Answer to the example: 20% of 200 is 40
Here is the solution to your problem:
The suit has a regular price of $270.
The percent off is 30%.
First, we find the dollar amount of the discount.
30% of $270 = 0.30 × $270 = $81
The dollar mount of the discount is $81.
Now we subtract the dollar amount of the discount from the original price of $270.
$270 - $81 = $189
Answer: The sale price is $189.

The function f is given by
f(x) = 2x^3– 4
(a) Show that f^-1(50) = 3
Answer:
hope it helps you.....
and I m feeling bad for my handwriting
The proof of the value of the inverse equation f^-1(50) = 3 is below
How to prove the value of the inverse equationFrom the question, we have the following parameters that can be used in our computation:
f(x) = 2x^3 - 4
To show that f^-1(50) = 3, we simply show that
f(3) = 50
substitute the known values in the above equation, so, we have the following representation
f(3) = 2 * 3^3 - 4
Evaluate
f(3) = 50
Hence, the proof of the value of the inverse equation is done
