The inequality is .
Now we find the intercepts
\First find y-intercept
\ (Replace x by 0)
(Simplify)
The y-intercept is .
Next find x-intercepts
\ (Replace f (x) = 0)
(
write as
)
(Take out common factors)
(Simplify)
(Apply zero product property)
(Simplify)
The x-intercepts are .
Graph the function
The vertex is at ,
(Simplify)
(Replace
)
(Simplify)
(Simplify)
The vertex is
Graph the solution set on a number line.
The solution set is .
