The graphs of $y=f(x)$ and $y=g(x)$ are shown in the $xy$-plane. The graph of $f(x)$ is a parabola opening upwards with its vertex at $(0,-2)$. The graph of $g(x)$ is a line that passes through $(0,-1)$ and $(2,1)$. The two graphs intersect at two distinct points.

For how many values of $x$ is $f(x)=g(x)$?
