has degree 3, so it takes the general form
It has a root of multiplicity 2, which means divides exactly, and it has a root of of multiplicity 1 so that also is a factor. So
Expanding this gives
The -intercept occurs for , for which we have
Then
So we have
Answer:
4
Step-by-step explanation:
on edge.
For , we have two cases:
Therefore, for , we have the following cases:
Solving, we have:
