Answer
(a) $x=-1$ and $x=4$
(b) no value
(c) $y=-1$
(d) $x=5$, $x=3$ and $x=0$
(e) Maximum value of $y$ is $9$ at $x=6$ and minimum value of $y$ is $-2$ at $x=0$.
Work Step by Step
(a) Use table and find values of $x$ corresponding to $y=1$.
We get $x=-1$ and $x=4$.
(b)Since, $3$ is not among the values of $y$ in the table.
There are no value of $x$ for $y=3$.
(c)Use table and find values of $y$ corresponding to $x=3$.
We get $y=-1$.
(d)Since, $y\leq0$
$y$ can be equal to zero or $y$ can be negative.
Use table and find values of $x$ corresponding to $y=0$ or $y$ being negative.
we get $x=5$, $x=3$ and $x=0$
(e) Use table to find the maximum and minimum values of $y$.
We get maximum value $9$ and minimum value $-2$.
Now, use table and find value of $x$ corresponding to $y=9$.
We get $x=6$.
Now, again use table and find values of $x$ corresponding to $y=-2$.
We get $x=0$.
