Given the definitions of f (x) and g(x) below, find the value of (gof)(-8). f(x) = -x + 8
g(x) = x2 – 3x+2

(gof)(-8) = 210

Step-by-step explanation:

(gof) = (-x + 8)² - 3(-x + 8) = 2

        = x² - 16x + 64 + 3x - 24 + 2

        = x² - 13x + 42

(gof)(-8) = (-8)² - 13(-8) + 42

             = 64 + 104 + 42

             = 210

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
