Question

Consider the functions f(x) = 5x2 and g(x) = 4(x + 8). Find f[g(−6)].

Answer 1

First input -6 into g(x)

Answer 2

then input the answer of g(x) into (f(x))

Answer 3

find g(-6) as the 1st step

g(-6) = 4(-6 + 8)

when you get that value

find

f(value)

Answer 4

g(-6) = 8?

Then to get f(value):

f(-6) = 5*-6*2 ?
