When you see composite functions you need to think of it as two different problems. The inside and the outside. So for the first one: \[(gof)(x)\] Is going to first be \[f(x)\] And then the answer for that will go into \[g(x)\] When you do not have a value for x it can be tricky. Take the f(x). \[f(x)=6x-3\] Now the value that you have will be plugged in where the x is in g(x). \[g(f(x)) = \frac{ 1 }{ 3 }(6x-3) +5\] And then you simplify the right side.

last part is complicated, but i'll try anyways. and Thanks!

It is complicated when you do not have a value for x, so make sure to take your time and write out each step so you do not forget something.
