Question
The image presents a graph with a piecewise function and asks to express this function in its mathematical form. Below is a detailed description and transcription based on the content of the image:

### Graph Description

The graph consists of two distinct linear segments:

1. **Left Segment:**
   - **Line:** Starts at the open circle on the y-axis at \( y = 10 \), moving downward with a negative slope, until it reaches a point just before \( x = -2 \).
   - **Line Equation:** This segment can be approximated as a line with a negative slope.
   - **Domain:** \( x < -2 \).

2. **Right Segment:**
   - **Line:** Begins at an open circle on the graph at \( x = 2, y = 3 \) and moves with a negative slope, going through \( x = 10 \).
   - **Line Equation:** This segment appears as a straight line trending downward.
   - **Domain:** \( x \geq 2 \).

### Piecewise Function Representation

The function \( f(x) \) can be expressed in a piecewise manner, capturing the behavior described above:

\[ 
f(x) = 
\begin{cases} 
-3x - 4 & \text{for } x < -2 \\
-x + 3 & \text{for } x \geq 2
\end{cases}
\]

### Explanation

- For the domain \( x < -2 \), the corresponding line segment has a formula possibly representing a negative slope that decreases as x decreases. The line starts from \( y = 10 \) on the y-axis.
  
- For the domain \( x \geq 2 \), the line follows a downward slope. It starts from a point above the axis and ends extending towards the negative y-values as x increases.

Note: The exact equations are approximations based on typical linear function format \((y = mx + b)\), matching the pattern observed on the graph where \(m\) is the slope and \(b\) is the y-intercept.

Expert Solution
Step 1

The stepwise function is the function that has different values for different values of x. The stepwise function may be discontinuous at some intervals.

The equation of a line can be obtained using two points form y-y1=y2-y1x2-x1x-x1. Here, the points are x1, y1,x2, y2.
