ok..

Answer 6

then after you find that one out the second one we need to do is 5f(x)

Answer 7

f(x)=3x-2
therefore
f(5x)=3(5x)-2 =15x-2

Answer 8

so far so good that's what i have for the first

Answer 9

now for the second one i have 15x-10

Answer 10

f(x)=3x-2
therefore
5f(x)=5(3x-2 ) =15x-10
thus
5f(x) =15x-10
