Question

The graph of the function f is shown below.

Of the following options, at what values of x is the function f NOT differentiable?

Options

• At x = 0 and x = 2

• At x = 1 and x = 3

• At x = – 1 and x = 1

• At x = – 1.5 and x = 1.5

Answer 1

At x = 0 and x = 2

Explanation:

Hence, x = 0 and x = 2, the function f is not differentiable.
