if you subtitute 1 y value into the graph, how many possible x value corresponds to that y value?

lets say y = 0, at y = 0 what will be the value of x according to the graph?

Just look at the Domain and Range of the graph. This question will make a lot sense if you pay attention to the wording

The Domain is X E R

The Range is Y E R
