To accurately select the piecewise function based on the description provided, let's analyze the characteristics of each segment:
-
For x < -1: The description mentions that there is a ray with a closed endpoint, indicating that this line segment is included at x = -1. Therefore, if it has a slope that leads to a value on the y-axis, we can conclude it could be of the form \(x + 2\).
-
For -1 ≤ x ≤ 1: Since there is a closed endpoint at both -1 and 1, it indicates that the function includes values in this range, taking a form like \(x + 3\).
-
For x > 1: The ray for this section has a closed endpoint at 1 and extends indefinitely. Thus, it should take the form of \(x + 1\) since it starts from 1.
Based on this information, the correct piecewise function is:
\[ y = \begin{cases} x + 2 & \text{for } x < -1 \ x + 3 & \text{for } -1 \leq x \leq 1 \ x + 1 & \text{for } x > 1 \end{cases} \]
This matches the first response option:
y=⎧⎩⎨⎪⎪x+2, x<−1 x+3, −1≤x≤1 x+1, x>1
So, the correct choice is the first option.
