I got these questions wrong in my test. Can someone explain this to me please???

f(x)-->(3x-2)/(x+2)

Find f '(x)

Find f '(2)

f:x-->2x+5, g:x-->(1/2)x

Find f(g:x)

Find g(f:x)

That is what I don't know. It came in the test but the teacher didn't teach this because he left the school without completing the syllabus. Please teach it....

the first question involves calculus ...

**taking the derivative of a rational function f(x) using the quotient rule**, then evaluating the value of that derivative f'(x) at x = 2, f'(2).

I believe the second function involves**function composition**.

I recommend you google**the above topics**and research how to do them yourself.
