Let f(x) = x Then the expression -5 where A is a constant and A= f'(x) = lim h→0 Using your answer from above we have: f(x+h)-f(x) h f' (3)= f(x+h)-f(x) h = Finally, find each of the following: f'(1) = f'(2) = can be written in the form A x(x +h)

help need the answer for top and bottom its not.      -10x/(3+x^2)^2

f(x) = 2 sinx+1 2. What are two similarities and two differences between Use proper terminology and mathematical notation in your explanation. and g(x) = 2 cscx+1

Consider the following function.   f(x) = (2x + 6)5   (a)Make a sign diagram for the first derivative. (b)Make a sign diagram for the second derivative.
