when I have (2x^(3)-18x)-(2x^(3)) / (x^(2)-9) am I suppose to be left with -18x/(x^(2)-9) or is it just 18x? Please help and thanks!

Use differential, i.e., linear approximation, to approximate (125.4^(1/3)) as follows: Let f(x)=x^(1/3) . The linear approximation to f(x) at x=125 can be written in the form y=mx+b where m is: m=1/75 b=? How do I find b?

Consider the function f(x)=8(x^(1/2))+7 on the interval [1,5]. By the Mean Value Theorem, we know there exists a c in the open interval (1,5) such that f'(c) is equal to this mean slope. For this problem, there is only one c that works. Find it.
