Hello, r-soy!

Eyeballing the graph, the answers seem to be:

. . $\begin{array}{cccc}29)\;\;y \:=\:7 &&& 30)\;\;y \:=\:-4 \\ \\

31)\;\;x \:=\:\text{-}5,\,\text{-}1,\:6 && & 32)\;x \:=\:\text{-}6,\,1,\,5 \end{array}$

I've modified your graph a little bit.

The rectangle in the equation contains the initial value, the results are indicated in the graph.

In red: x-value is known, y-value must be found.

In blue: y-value is known, x-value(s) must be found.
