To determine the correct piecewise function from the graph described, we need to analyze the endpoints and behavior of each segment:

  1. For \(x < -1\), if the ray has a closed endpoint at \((-1, y)\) and a linear behavior observed in the graph, the expression could be something like \(y = x + 2\).

  2. For \(-1 \leq x \leq 1\), if this segment is a line from \((-1, y)\) to \((1, y)\), we see that segments could be defined by a function, possibly \(y = x + 3\), since this fits the linear path over that instantiation.

  3. For \(x > 1\), if this ray is open on its endpoints after \(x = 1\) and going upwards, it might be \(y = x + 1\).

Given these observations about endpoint inclusivity and exclusivity, the piecewise function can be reconstructed:

The correct choice is: \[ y = \begin{cases} x + 2, & \text{if } x < -1 \ x + 3, & \text{if } -1 \leq x < 1 \ x + 1, & \text{if } x \geq 1 \ \end{cases} \]

This aligns with the fourth option from the provided responses:

y = ⎧⎩⎨⎪⎪x + 2, x < −1; x + 3, −1 ≤ x < 1; x + 1, x ≥ 1.

This is the most likely equation based on your description of the graph characteristics.
