Answer

$f(-3,3)$ is roughly $56$. $f(3,-2)$ is roughly $35$.

Work Step by Step

The value of the function f at point $(-3,3)$ is larger than $50$ and smaller than $60$. It is closer to $60$, so $f(-3,3)$ is roughly $56$. The value of the function f at point $(3,-2)$ is between $30$ and $40$. $f(3,-2)$ is roughly $35$. The values of f are increasing as we approach the point $(0,0.5)$. The values increase more rapidly from below the x axis.
