Problem 28
On the same set of axes are drawn the graph of and the graph of the equation obtained by replacing
by
in the given equation.
If
and
these two graphs intersect:
Solution
Replacing with
we have the graph of
We can plug in simple values of and
for convenient drawing. For example, we can graph
and
We see that the parabolas intersect at
which is on the y-axis.
The answer is
