Question

how do you solve this?

Let f(x) = x - 2 and g(x) = x2 - 7x - 9. Find f(g(-1)).

Answer 1

first find g(-1) then use that answer to plug it into f.

Answer 2

how do i find g(-1)

Answer 3

since \(\large g(x) =x^2-7x-9 \), then \(\large g(-1)=(-1)^2-7(-1)-9= \) simpify.
now plug this answer into f(x) by doing the same thing with f(x)
