Answer:
This means the function touches the x-axis at -1 but does not cross.
Step-by-step explanation:
A polynomial graph has several features we look for to determine the equations.
- The zeros of the function are the x-intercepts. If the x-intercepts touch but do not cross then the intercepts have an even multiplicity like 2, 4, 6, etc. If the x-intercepts cross over then they have an odd multiplicity.
- Vice versa. If I know the zero and multiplicity, I can make an accurate sketch of the functions behavior.
This means the function touches the x-axis at -1 but does not cross.
