Is the function integrable? Do you know the formula for the average value of a function?

### dan greig

the curve is,

y=10/x^2

i have already found the area under the curve between two points by changing this to,

10x^-2

no i don't know the formula?

Average value of an integrable function on the closed interval [a,b] can be found via

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