Let f be defined as follows.
y = f(x) = x^2 - 4 x

(a) Find the average rate of change of y with respect to x in the following intervals.

from x = 5 to x = 5.5
For some reason I keep getting this wrong. The way I did it was: f((5.5)-f(5))/(x2-x1)= 22-5/5.5-5=34 This is wrong, could someone show me what I'm doing wrong?
