Р p+k
a) Think about an interval on the x-axis starting with p and ending with p + k. What is the
difference between the x-values? What is the difference between the y-values for these
y = -
--**-
x-values? Complete the tables using
Interval between p = 2 and p + k = 6

b) The difference in the x-values for each interval is _4_. This value is constant because
difference = (p + k) - p = _K_.
