Answer 6

1 for the first question

Answer 7

to get that you plug in 0 into g(x) then plug your solution 0 into f(x)

Answer 8

and you get 1

Answer 9

I didn't say don't explain

Answer 10

Thank you @marvin.cling

Answer 11

i explained do you want more explanation?

\[g(2)=2(2)-4=0, f(g(2))= 3(0)+1=1. How's that for an explanation\]

Answer 12

sorry i meant two not 0

Answer 13

no just plaese answer my next post
