Answer:
Graph at the bottom right.
Explanation:
From the given piecewise function,
1). y = -2 if x ≤ 1
An arrow representing this function will be parallel to x-axis with a dark circle at x = 1.
2). y = 1 if 1 < x ≤ 2
A straight line representing this function will be parallel to x-axis with a dark circle at x = 2 and a hollow circle at x = 1.
3). y = 3 if x > 2
An arrow representing the function will be parallel to the x-axis having one end as a hollow circle at x = 2.
Therefore, Graph at the bottom right will be the answer.
