Short Answer

Each function in Exercises 9–12 is discontinuous at some value x = c. Describe the type of discontinuity and any one-sided continuity at x = c, and sketch a possible graph of f.

limx2-f(x)=-, limx2+f(x)=, f(2)=3.

The type of discontinuity is an infinite discontinuity and there is not any one-sided continuity.

The graph of f is

Step by Step Solution

Step 1. Given Information. 

The given function is limx2-f(x)=-, limx2+f(x)=, f(2)=3.

Step 2. Describing the discontinuity. 

From the function, we can depict that f(x) has infinite discontinuity because both of limx2-f(x) andlimx2+f(x) are infinite.

Step 3. Describing one-sided continuity at x=c.

There is not any one-sided continuity at x=2 because limx2-f(2) and limx2+f(2).

Step 4. Graph of f.

The graph of f is
