Points of intersection ​

Notes ​

In the picture below, $A$ and $B$ are points of intersection between

and

Notice that there could be either $2,1$ or $0$ points of intersection depending on the position of the line.

When there is only one point of intersection, we say that the line is a tangent to the parabola:

We're going to learn to find points of intersection, and solve problems about points of intersection.
