The inequality 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 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
.
