# Find the average rate of change f(x) = \sqrt{2x + 2 } between x =1 and x = 7.

## Question:

Find the average rate of change {eq}f(x) = \sqrt{2x + 2 } {/eq} between {eq}x =1 {/eq} and {eq}x = 7. {/eq}

## Rate of change

For a function {eq}\displaystyle y=f(x) {/eq} defined over the interval {eq}\displaystyle (a,b) {/eq}

The average rate of change of function is defined as {eq}\displaystyle \frac{f(b)-f(a)}{b-a} {/eq}
