Answer:
The average rate of change of function is -4 in [1,3]
Step-by-step explanation:
The average rate of change for graphic quadratic function for the interval from x=1 to x=3
The average rate of change of a function is change y over change in x.
[tex]\text{Average rate of change of function}=\dfrac{f(b)-f(a)}{b-a}[/tex]
where,
a=1 and b=3
Using graph we will find f(1) and f(3)
f(3)=-8
f(1)=0
[tex]\text{Average rate of change of function}=\dfrac{f(3)-f(1)}{3-1}[/tex]
[tex]\text{Average rate of change of function}=\dfrac{-8-0}{2}=-4[/tex]
Hence, The average rate of change of function is -4 in [1,3]
