Given function :.
We need to find the average rate of change from x = −2 to x = 0.
Let us find the values of y-coordinates for x=-2 and x=0 for the given function on the graph.
Formula for average rate of change is :
Plugging the values of f(a), f(b), a and b in the above formula, we get
.Therefore, the average rate of change from x = −2 to x = 0 is .
the standard deviation is around 0.6.
