Question

Find the rate of change for each interval solve 2

Answer 1

we will use the next formula to find the rate of change of the given interval

`r=(f(b)-f(a))/(b-a)`

in our case

a=-3

b=6

`f(-3)=10\log (-3+4)+2=2`

`f(6)=10\log (6+4)+2=12`

then we substitute the values in the formula

`r=(12-2)/(6-(-3))=(10)/(6+3)=(10)/(9)`

The average rate of change is 10/9=1.11
