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) NEED HELP!!!
