{x}^{2}  - 16 = 0 \: is \: the \: equation

Step-by-step explanation:

x =  - 4 \\ or \: x = 4

(x + 4) = 0 \: or \: (x - 4) = 0 \\ (x + 4)(x - 4) = 0 \\ open \: the \: bracket

x(x - 4) + 4(x - 4) = 0

Given the definitions of f(x) and g(x) below, find the value of (fog)(-8).
Masja [62]

Answer:

(f \circ g)(-8) = 16

Step-by-step explanation:

The given function are;

f(x) = x² - 3·x - 12, and g(x) = -x - 12

(f \circ g)(x) = f(g(x))

Therefore;

(f \circ g)(-8) = f(g(-8))

g(-8) = -(-8) - 12 = 8 - 12 = -4

∴ f(g(-8)) = f(-4) = (-4)² - 3×(-4) - 12 = 16

Therefore;

(f \circ g)(-8) = f(g(-8)) = 16
