Answer
(a) $-\frac{3}{2},\frac{9}{2}$.
(b) $[-\frac{3}{2},\frac{9}{2}]$.
(c) $(-\infty,-\frac{3}{2})\cup(\frac{9}{2},\infty)$.
Work Step by Step
See graph for the two given functions.
(a) We can identify the solution as $x=-\frac{3}{2},\frac{9}{2}$.
(b) We can identify the solution as $[-\frac{3}{2},\frac{9}{2}]$.
(c) We can identify the solution as $(-\infty,-\frac{3}{2})\cup(\frac{9}{2},\infty)$.
