To solve the equation $f(x)=2$ means that we should determine the $x$-values for which the function equals $2.$ We will do that by drawing the line $y=2,$ and then identify the points of intersection.

The points of intersection between graph of $f(x)$ and the horizontal line tells us that $f(x)=2$ at $x=-6$ and $x=0.$

To solve the equation $f(x)=g(x)$ means that we should determine the $x$-values for which $f(x)$ and $g(x)$ are equal. They will be where the graphs intersect each other. In the figure we see that it occurs at $x=-6$ and $x=2.$
