Question

Problem: For each of the ff functions, find the expression for f(x+h)-f(x)/h.
Simplify each of your expressions far enough so that plugging in h=0 would be allowed.

(a) f(x)=x^2-2x
(b) f(x)=2x+3
(c) f(x)=x^2-3
(d) f(x)=4-x^2
(e) f(x)=-πx^2-π^2
(f) f(x)=√(x-1) (Hint: Rationalize the numerator)
