Answer:
1 < x ≤ 2
Step-by-step explanation:
A graph's slope equals zero when there is a change in the x-value, but there's no change in the y-value.
Here, we can see in the piecewise function that between 1 (not included) and 2 (included), the slope of the graph is 0.
Therefore, 1 < x ≤ 2 is correct
