Question

If f(x)=2x, g(x)=2x-1, and h(x)=square root of x, find (f o g o h)(9)
I think I have the right answer, but can someone please reassure me?

Answer 1

h(9)= sqrt of 9 which is 3. Now plug 3 into g(x).

Answer 2

2(3)-1= 6-1=5. Now plug 5 into f(x).

Answer 3

2(5)=10. The answer is 10. Did you get that?

Answer 4

@IMStuck Yes. I did. Thank you! I did it wrong the first time so I wanted to be sure.

Answer 5

Good for you! God job!
