Average rate of change of function f(x) = x^2 +2 over the interval x= -5 to x= -2 is -7
Step-by-step explanation:
We need to find the average rate if change in the function f(x) = x^2 +2 over the interval x= -5 to x= -2
The formula used to find the change of average rate is:

Where b= -2 and a= -5
Finding f(b) and f(a)
f(b)=f(-2)=(-2)^2+2=4+2=6
f(a)=f(-5)=(-5)^2+2=25+2=27
Putting values in the formula:

Average rate of change of function f(x) = x^2 +2 over the interval x= -5 to x= -2 is -7
