Hi,

when finding maximum point of graph, where do I look at? The y axis or the x axis?

Also, the answer should be "x=7" (for example), am I right?

Thank you

A point has always 2 coordinates if you're working in a plane, so a maximum $\displaystyle M$ could be for example $\displaystyle M(7,4)$.

But for example $\displaystyle x=7$ can't represent a point, it represents a line (parallel to the y-axis).

Do you mean the $\displaystyle y-$axis itself? It's just $\displaystyle x=0$.
