To find the y-intercept of h(r), plug in 0 for r, and solve:
h(r) =
r - 5
h(r) =
× 0 - 5 <em>(plug in 0 for r and solve)</em>
= h(r) =
-5So the y-intercept for h(r) is:
-5
-------------------------------------------------------------------------------------------------------------
For p(r), the y-intercept is when x = 0.
From looking at the table, we see that when x=0, p(r) =
-5
So the y-intercept of p(r) =
-5-------------------------------------------------------------------------------------------------------------
ANSWER:
The y-intercept of h(r) and p(r) are both equal to
-5, therefore the y-intercepts
are the same.
So the answer would be:
c) The functions have the same y-intercept.
