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.
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.
