F (x) = - 1

g (x) = x-4

Can you evaluate (gof) (o) ? Explain why or why

not.

Answer: Yes. (gof) (0) = - 5

(gof) (0) means you will find the function of g (f (0)), which means we will find f (0) and plug that value in for x in the function g (x)

We know f (0) is - 1, so we can plug - 1 into the equation of g (x)

(gof) (0) = (-1) - 4

(gof) (0) = - 5
