Answer: {y∈R: y≤6} or [6,∞)
Explanation:
This problem doesn't require too much math. If you look at the equation given, you can see that it is a quadratic equation in the form of[tex]y=Ax^2+Bx+C[/tex]. Since this is a quadratic equation, we have an idea of that the graph would look like. It either curves up or down. Since this is a positive equation, [tex](+3x^2)[/tex], we know that this is going to curve up. In order to find the minimum of the curve, you would use [tex]\frac{-b}{2a}[/tex].
[tex]\frac{-12}{2(3)}=-2[/tex]
This means the x value of the parabola is -2. To find the y, you plug -2 into the original equation.
[tex]f(2)=3(-2)^2+12(-2)+18[/tex]
[tex]f(2)=6[/tex]
Now that we know the y value of the minimum/vertex is 6, and it is determined that the parabola curves up, the range is y≤6 because the range starts at 6 and goes off toward infinity.
In a certain Algebra 2 class of 21 students, 12 of them play basketball and 14 of them
play baseball. There are 5 students who play neither sport. What is the probability
that a student chosen randomly from the class plays basketball or baseball?
Answer:
Explanation:
We know there are 21 students in all, so that should be the denominator in this answer.
Then, to find the numerator, we need to find the number of students that play basketball and the number of students that play baseball, assuming that none of them play both sports. Just add those two numbers to get the numerator, and then put it on top of the 21.
You either typed this question incorrectly, or there is a mistake, because there are more kids that play basketball or baseball than there are students in the class.

Which areas does acid rain most likely form before rain
If a/b=1, what is the value of a-b?
Answer:
0.
Explanation:
If you do a=2 and b=2, then 2-2=0.
a/b=1
If you do a=2 and b=2, then 2-2=0.
a-b=0.
What is the absolute value of the ratio?If a and b are real numbers then, |-a| = |a| a number and its negative have the same absolute values. |ab| = |a||b| The absolute value of a product is the product of the absolute values. |a/b| = |a|/|b| The absolute value of a ratio is the ratio of the absolute values.
What is the a value in absolute value?The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
