Hello,

I've done this question but i am not sure if its correct.

Given that f(x)= 2x+1 and g(x)=3x-5 find the value of

a) fg(0) b) gg(4)

---Answer---

a) fg(0)= f(g(0))

g(0)= 3(0)-5

= - 2

f(-2)= 2(-2)+1

=-3

b) gg(4)= g(g(4))

g(4)= 3(4)-5

=7

f(4)= 2(7)+1

=15

Is my way and answer correct?

Thanks.
