The graph below is a plot of a function $f$ . What best describes the behavior of $f$ on the interval from $x=-2$ to $x=2$ ?

As $x$ increases, $f(x)$ is increasing at an increasing rate. As $x$ increases, $f(x)$ is increasing at a decreasing rate. As $x$ increases, $f(x)$ is increasing at a constant rate. As $x$ increases, $f(x)$ is decreasing at a decreasing rate. As $x$ increases, $f(x)$ is decreasing at an increasing rate.
