1. Consider the following function,
if x = 0
if x = 0
Prove that the function f is differentiable at x = 0 using the definition of
- {27² min (²2)
0
derivatives.
ƒ(x) =
(a)
(b)
Find the formula of the derivative, f'(x) for x # 0, using any differentiation
rules you have learned in this course. Indicate clearly which rules are used in your
computation.
Note: after this work, you may want to see if the derivative function is continuous at
x = 0. While the original function f is differentiable and so also continuous at x = 0, its
derivative is not continuous at x = 0.
