Question 311327: find the average rate of change of f(x)=x^2-4x+2 between x=-1 and x=3
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
Average rate of change = change in f(x) / change in x
Here
f(3) = -1
f(-1) = 7
so we plug in and get
avg rate = (7 - (-1)) / (-1 - 3) = 8 / -4 = -2
