Using the graph of $y = f ^{\prime\prime}(x)$ below, determine the intervals where $f$ is concave up and the intervals where $f$ is concave down.

Downward parabola, labeled f double prime of x, vertex at the point (negative 1, comma 4), passing through the intercepts, (negative 3, comma 0), (0, comma 3), & (1, comma 0).

Hint:

Notice that you are looking at a graph of $y = f ^{\prime\prime}(x)$ but being asked questions about the graph of $y = f(x)$ .
