It looks like you've uploaded an image containing a math worksheet titled
"10.2B: Piecewise Functions", which includes several problems related to
piecewise functions. Since I can't view images directly, I’ll need you to provide the content of the image (e.g., text or description of the problems) so I can help solve and explain them.
However, based on the title and typical structure of such worksheets, here’s what you might expect:

🔍 What is a Piecewise Function?
A
piecewise function is defined by different expressions over different intervals of the domain. For example:
$$
f(x) =
\begin{cases}
x + 1 & \text{if } x < 0 \\
x^2 & \text{if } x \geq 0
\end{cases}
$$

📌 Common Tasks in These Problems:
1.
Evaluate the function at specific values.
2.
Graph the piecewise function.
3.
Write a rule for a given graph.
4.
Determine domain and range.
5.
Identify continuity or discontinuity.

✔ Example Problem (Typical):
Suppose the problem says:
> Evaluate $ f(-2), f(0), f(3) $ for:
> $$
> f(x) =
> \begin{cases}
> 2x + 1 & \text{if } x < 1 \\
> x^2 - 1 & \text{if } x \geq 1
> \end{cases}
> $$
#### Solution:
- $ f(-2) $: since $-2 < 1$, use $2x + 1$:
$ 2(-2) + 1 = -4 + 1 = -3 $
- $ f(0) $: $0 < 1$, so $2(0) + 1 = 1$
- $ f(3) $: $3 \geq 1$, so $3^2 - 1 = 9 - 1 = 8$
✔ Answers: $ f(-2) = -3, f(0) = 1, f(3) = 8 $

📈 Graphing a Piecewise Function:
You might be asked to graph something like:
$$
f(x) =
\begin{cases}
-2x + 4 & \text{if } x \leq 1 \\
x - 1 & \text{if } x > 1
\end{cases}
$$
Steps:
1. Graph $ y = -2x + 4 $ only for $ x \leq 1 $ (closed dot at $ x = 1 $).
2. Graph $ y = x - 1 $ only for $ x > 1 $ (open dot at $ x = 1 $).
