Answer: -2
Step-by-step explanation: The average rate of a function f(x) from x=a to x=b is given as:
Clearly we are asked to find the average rate of change from x=0 to x=2.
i.e. a=0 and b=2
Also, from the graph it could be observed that:
f(0)=1
and f(2)=-3
Hence, the average rate of change is calculated as:
Hence, the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:
-2
