Answer: (C) 1
<u>Step-by-step explanation:</u>
The question is asking which y-value are not represented in the graph. IN other words, they are asking for which values are not included in the range.
You can do this by graphing the equations:
y = x + 2 for x ≥ 0 has a y-intercept of +2 with y-values increasing
- <em>Note: +2 is included so has an closed dot</em>
y = x - 2 for x < 0 has a y-intercept of -2 with y-values decreasing
- <em>Note: -2 is not included so has an open dot</em>
Therefore, there are no y-values between +2 and -2 (including -2). The only option provided between these values is 1, which is option C.
