The inequality function is .

.

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

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

.

The zeros of the function is .

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

Denominator of the function should not be zero.

The function is defined for all values of except at .

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 .
