Question

f(x)=3x-1 and g(x)=x^2+4. Find f(g(6))

Answer 1

Plug in 6 into g(6) and then plug in the answer of g(6) into f(x)

Answer 2

\[f(g(x))=f(x^2+4)=3(x^2+4)-1=\]

Answer 3

I keeep getting the answer wrong.

Answer 4

what are you getting?

Answer 5

g(6) = (6)^2 + 4 = 36 + 4 = 40.
f(40) = 3(40) - 1 = 120 - 1 = 119

Answer 6

how do i type that answer

I am doing practice questions on the computer and no matter how i write it it says its wrong?@

Answer 8

\[f(g(6))=f(6^2+4)=3(6^2+4)-1=\]

Answer 9

@UnkleRhaukus and @vintageballad are right

Answer 10

i didnt know if there was another way to write the answer

Answer 11

Answer 16

I think I am confusing myself

Answer 17
