Evaluating/Simplifying an Expression

[kingpie]

Part f. is the only expression I am unsure of what steps to take to get the correct answer.

Would anyone be willing to give me an idea?

If you have done (e), then you have an expression for f(x+h).
So now subtract f(x) from that (you may need to expand first) and simplify.
The denominator can be simplified very easily.
Can you cancel any common factors?

Can you make the picture a little fuzzier, please? I can almost read it.

The best thing you can do here is to show us your work as far as you have attempted it (including, as Harry said, your answer to part (e)). The distributive property will be very important.

Excuse the blurry images, I don't have the best camera to take pictures with at the moment. In either sense, this is where I am at currently. Anything incorrect so far?
Also, I wrote the part (e.) piece again for this problem since my teacher wishes for all the steps to be shown, no matter if I had done it in a previous problem.

Ok good now simplify the denominator and see if anything cancels.
