Short Answer

For each function f graphed in Exercises 65-68, determine the values of x at which f fails to be continuous and/or differentiable. At such points, determine any left or right continuity or differentiability. Sketch secant lines supporting your answers.

The function is not continuous at x=-1 and non-differentiable at x=-1 and the secant lines is

Step by Step Solution

Step 1. Given information

Given the graph

Step 2: See the point at which there is a sharp point

From the graph, the function is having a sharp point at x=-1 at which is not continuous and not differentiable at x=-1

The secant lines are
