Question
For each graph,
a. Describe the end behaviour.
b. Determine whether it represents an odd-degree or an even-degree polynomial function, and
c. State the number of real zeros.
Step-by-Step Solution
Verifieda. It goes upwards on the right and goes downwards on the left.
b. It is an odd-degree polynomial function.
c. There are 5 real zeros.
Given graph is:
We have to describe the end behaviour.
From the graph,
It goes upwards on the right and goes downwards on the left.
Given graph is:
We have to determine whether it represents an odd-degree or an even-degree polynomial function.
From the graph,
It goes downwards on the left and goes upwards on the right.
Since it goes to two different sides on both ends, so it must be an odd-degree polynomial function.
Given graph is:
We have to state the number of real zeros.
From the graph,
It cuts the x-axis 5 times. So there are 5 real zeros.
