The inequality is .

Determine the real zeros of ( -intercepts of the graph) and the real numbers for which is undefined :

The zeros of the function are the values of for which .

.

The zeros of the function is .

Use the zeros found in Step 2 to divide the real number line into intervals.

The function intervals are and .

Since there is real zero, divide the - axis into two intervals.

 Choose a number for in each interval and evaluate .
