1. Problem Description
We are given the equation . We are also given that . We want to find the coordinates of the intersection points of the parabolas and .
2. Solution Steps
Since we want to find the intersection points of and , we need to solve , which is equivalent to .
We are given that .
Substituting , we have
.
We want to solve , so we have
.
Multiplying by , we get
.
This factors as , so .
Now we need to find the -coordinate. Since , we can write . To find the -coordinate, we need more information about or . Let's look back at .
Let's express as .
Since , we know that .
We still need to find the corresponding -coordinate. However, we can write at the intersection point. Let .
It appears that we need more information about either or to find . Let us assume that the intended problem means to find the -coordinate of the intersection and the value of at .
The -coordinate is .
.
So we have the point , but we need to find a such that . Since when , we know that the -coordinate of the intersection satisfies . Let .
We have that . Then , so let's differentiate with respect to :
.
At , .
We want to find .
Since we can only find , there might be something wrong with the question.
Assuming that , and letting , we find . We know that , so let's suppose that and are tangent to each other at .
We want to solve the equation . Substituting , we get , so , which yields . Thus .
The -coordinate is . When , , so they intersect.
We are looking for .
. Since we have and we know that , we need more information to solve the -coordinate. However, when , , which doesn't make sense. However, since , then .
