Let f(x) = = 1 X 1 Use the limit definition of the derivative to find (i) f'(-3) = (ii) f'(0) = (iii) f'(2) = (iv) f'(4) = To avoid calculating four separate limits, I suggest that you evaluate the derivative at the point when x = a. Once you have the derivative, you can just plug in those four values for "a" to get the answers.
