Question

Very confused..

Answer 1

This means that you need to find the value of f(g(3)) and the value of g(f(-2))
You can do this one of two ways. First you can substitute the equation for g into f then substitute 3.
It would look like this:
2(x+1)-3= f(g(x))
2x+2-3 = f(g(x))
2x-1 f(g(x))
Then substitute 3.
2(3)-1=
6-1=
5
OR
You can substitute 3 into g and then substitute the value of g into f.
That would look like this:
g(3) = 1(3) + 1
g(3) = 3+1
g(3) = 4
Then substitute the value of g(3) into f(x) or f(g(3))
f(g(3)) = 2(4)-3
f(g(3)) = 8-3
f(g(3)) = 5
Any questions?

Answer 2

Nope. Thank you for the concise directions! That really helped.
