Let f(x)=x^2+3x+2 .
What is the average rate of change of f(x) from 3 to 6?
f(3) = (3)^2 + 3(3) + 2 = 20
f(6) = (6)^2 + 3(6) + 2 = 56
Avg rate of change from 3 to 6 = [ f(6) - f(3) ] 56 - 20 36
___________ = _______ = ___ = 12
6 - 3 3 3
2) Avg rate of change from - 2 to 2 = [ 9 - 25 ] -16
_______ = ____ = - 4
2 - (-2) 4
