You first have to find the equation of the quadratic function, hint use the intercepts.

After you have the function you can take the derivative to get the function f'(x) defining the rate of change of the graph.

You then apply the formula for the average value of a function over an interval which is,

$$f_{avg}(x) = \frac{1}{b-a}\int_{a}^{b} f(x) dx$$

where b=3 a=1 and f(x) = f'(x).

This should then yield the average rate of change for the function over the given interval.
