The graph of and the graph of
meet in two points. The distance between these two points is:
Solution
We can merge the two equations to create . Using either the quadratic equation or factoring, we get two solutions with
-coordinates
and
.
Plugging this into either of the original equations, we get and
. The distance between those two points is
