Question

Let g(y)= - y2 +9y + 10. Find g(-2).

Answer 1

Explanation:

g(y) = -y^2 + 9y +10

g(-2) = (-2)^2 + 9(-2) +10

g(-2) = 4 - 18 + 10

g(-2) = -4

Answer 2

`g(x)=-y^2\text{ + 9y + 10}`

To find g(-2)

We will have to replace y in the function with -2

`g(-2)=-(-2)^2\text{ + 9(-2) + 10}`

g(-2) = - 1x 4 + 9 x -2 + 10

g(-2) = -4 -18 + 10

g(-2) = -22 + 10

g(-2) = -12
