Hey guys,

I have a math assignment due on Monday, and I'm having difficulties understanding what two of the questions are asking.

My instructor didn't really go over questions like these all that much in class, so I'm not entirely sure what the question is asking. I have a similar issue with this question:1) Calulcate f(x+h) when:

a) f(x)=x^2

...

In each case, write down the corresponding expression for f(x+h) - f(x). Replace the right side of the equation with x+h for each instance.

Is this just asking to find (1/(1-x)^2)/t?2) If f(x)=1/(1-x)^2, find f(x/t).

Any help would be greatly appreciated!
