Step 1:
\The rational inequality is , where the rational function
.
The graph of rational functions can be recognized by the fact two or more parts.
\Step 2 :
\ the rational function is .
Find the - intercept by substituting
in the rational function.
.
There is no - intercept for the rational function.
Step 3 :
\Find the - intercept by substituting
in the rational function.
The - intercept is
.
Step 4 :
\Vertical asymptote can be found by making denominator is equals to zero.
\Vertical asymptotes are .
Step 5 :
\To find the horizontal asymptote, first find the degree of the numerator and the degree of denominator.
\Degree of the numerator = 1 and the degree of denominator = 2.
\Since the degree of the numerator is less than the degree of the denominator, is the horizontal asymptote.
is the horizontal asymptote.
Step 6 :
\Need some more points to more accurate graph.
\Choose random values for and find the corresponding values for
.

Step 7 :
\Graph
\1) Draw the coordinate plane.
\2) Next dash the horizontal and vertical asymptotes
\3) Plot the ,
intercepts and coordinate pairs found in the table..
4) Connect the plotted points with smooth curves
\Step 8 :
\First determine the intervals of such that the graph is above the
- axis from the graph.
From the graph, observe that, for
.
The solution set is .
Solution :
\The solution set is .
