Question

Let f(x)=x^2+2 and g(x)=1-3x Find each function value. f(g(-4))

Answer 1

171

Explanation:

First you plug -4 into the g(x) equation

g(-4)= 1-3(-4)

Use pemdas

g(-4)= 1+12

g(-4)= 13

Next you plug 13 into the f(x) equation

f(13)= 13^2 + 2

First you do 13^2=169

Add 2 and you get 171
