Hello all,

I have been doing a difference quotient problem for homework and can't seem to get it right.

The problem is this:

Find f(x+h)-f(x)/h where h=/=0 given the function x^2-x+4.

By following my teacher's instructions I did this and got this answer:

However, I am told the problem is wrong, and I have tried doing it several times, and I can't seem to get the correct answer..

Any help would be greatly appreciated.

Thank you very much in advance.

Edit:

While looking at the problem I found a place where I made a mistake and I still got the wrong answer having taken that mistake into consideration:

the mistake was where -(x^2-x+4) were concerned the correct way would have been -x^2+x-4 not -x^2-x-4.

After doing that I get the answer 3x+h which is also incorrect.
