Question

How do you find the average rate of change of `f(x)=-3x^2+2` between [-3,5]?

Answer 1

Average rate of change `= -6`

Explanation:

Average rate of change `= (Delta f(x))/(Delta x)`

For the given case, average rate of change

`color(white)("XXXX")=(f(5) - f(-3))/(5-(-3))`

`color(white)("XXXX")=((-73)-(-25))/8 = (-48)/8 = -6`
