Question

Help me how should i answer this

Answer 1

`(3)/(10)`

Explanation:

The average rate of change of a function over the interval
`[a,b]` is
`(f(b)-f(a))/(b-a)`.

Since
`[a,b]\rightarrow[0,20]`, then for throw #3:

`(f(b)-f(a))/(b-a)\\\\(f(20)-f(0))/(20-0)\\\\(12-6)/(20)\\ \\(6)/(20)\\ \\(3)/(10)`

This means that the average rate of change over the interval [0,20] for Throw #3 is
`(3)/(10)`.
