It looks like you've uploaded a worksheet titled
"Identifying Zeros" that contains multiple graphs of polynomial functions, and the task is to
identify the zeros (also known as roots or x-intercepts) of each function.
Since I can't view images directly, I'll guide you on how to solve this type of problem step-by-step. If you can describe the graphs or provide details about them (e.g., where they cross the x-axis), I can help you identify the zeros.

🔍 How to Identify Zeros from a Graph
The
zeros of a function are the
x-values where the graph crosses or touches the x-axis (i.e., where $ y = 0 $).
Here’s how to find them:
1.
Look at the x-axis: Find all points where the graph intersects the x-axis.
2.
Read the x-coordinates of those points — these are the
zeros.
3.
Note multiplicity (optional, but helpful):
- If the graph
crosses the x-axis: zero has
odd multiplicity.
- If the graph
touches and turns around (bounces): zero has
even multiplicity.

✔ Example:
Suppose one graph crosses the x-axis at $ x = -2 $, $ x = 1 $, and $ x = 3 $. Then the zeros are:
- $ x = -2 $
- $ x = 1 $
- $ x = 3 $
If it only touches at $ x = 1 $ and crosses at $ x = -2 $, then:
- $ x = 1 $ is a
double root (multiplicity 2)
- $ x = -2 $ is a
single root (multiplicity 1)

📌 Instructions for You:
Please describe
each graph (or tell me which ones you’re having trouble with), including:
- Where the graph crosses the x-axis
- Whether it crosses or just touches
- The scale of the axes (if not standard)
For example:
> "Graph 1: It crosses the x-axis at -3, 0, and 2."
Then I can give you the exact zeros and explain each one.
Alternatively, if you can list the coordinates of the x-intercepts from the graphs, I’ll format the answers neatly.
