for f(x)=x^2 +1, which value is the largest magnitude?
a) average rate of change from x=1 to x=1
b) instanteneuous rate of change at x=3
c) instanteneous rate of change at x=0
average rate of change from x=4 to x=0

a) (f(1)f(1))/(1  (1)) = 0
b) f'(x) = 2x. f'(3) = 6
c) f'(0) = 0
d) (f(0)f(4))/(0(4)) = 4
pick the greatest magnitude.
