Answer:
g(-7) = 57
Step-by-step explanation:
note: the editor will not let me use eff of x. I have to use g(x)
Equation
g(x) = -2x^2 -4x + 13
Comment
y is the same thing as g(x) so you are really being asked to find y,
Given
x = - 7
g(-7) means that x is -7
Solution
g(x) = -2(-7)^2 - 4(-7) + 13 Substitute x = - 7 on the right
g(x) = -2*49 + 28 + 13 Combine
g(x) = -98 + 28 + 13
g(-7) = -57
