The image shows a piecewise function graph and its corresponding equation with some given inequalities for $x$. Let's analyze the graph and the equations provided.

Graph Description:

• There are three segments in the graph.
  • The first segment is a horizontal line at $y = 0$ for $x \leq -3$.
  • The second segment appears to be a line with a positive slope from approximately $(-3, 0)$ to $(4, 1)$.
  • The third segment is a line with a negative slope starting from $(4, 1)$ for $x > 4$.

Given Piecewise Equations:

• The equations corresponding to the three segments are as follows:
  • $y = 0$ for $x \leq -3$ (correct based on the graph).
  • $y = \frac{2}{7}x + \frac{1}{7}$ for $-3 < x \leq 4$.
  • $y = -\frac{1}{3}x - \frac{1}{3}$ for $x > 4$ (this part seems to have an error in the equation or boundaries).

Error in the Third Equation:

The red box indicates that the equation for the third segment is incorrect. Based on the graph, the line starting from $(4, 1)$ has a different slope than the one shown in the provided equation. We can attempt to correct the slope based on visual analysis of the graph.

Correcting the Slope:

Let’s calculate the slope of the third segment:

• The line passes through the points $(4, 1)$ and appears to have a negative slope going downwards. We can approximate the slope visually or based on exact graph points.

Would you like me to help correct the third equation based on the graph analysis?

Let me know if you have any questions, and here are some related problems:

1. How do you find the slope of a line between two points?
2. How do you write a piecewise function based on a graph?
3. What are the conditions for determining the continuity of piecewise functions?
4. How do you solve a system of inequalities involving piecewise functions?
5. How can we test if the given function is a valid piecewise function?

Tip: When analyzing piecewise functions, make sure each part of the function satisfies the given conditions for the range of $x$ values.
