Find the average rate of change of f(x)=x^2-8x-7 from x to x+h

 

[srmichael]

For a function, f(x) on an interval [a,b], Average Rate of Change = \(\displaystyle \frac{f(b)-f(a)}{b-a}\).

Can you use this now on what you have?

I can't really tell what you need. You keep posting exercises with no effort or interest shown.

Please read the post titled "Read Before Posting".

Thank you!
