Question

What is the range of the function graphed below?

Answer 1

Answer: Choice B

Range = $-3 < y \le 3$

===================================================

Explanation:

The range is the set of all possible y values of a function.

The lowest point happens when y = -3. We exclude this y value because of the open hole.

The highest point is at y = 3 which is included because of the filled in circle.

The range can be written as $-3 < y \le 3$ meaning y is between -3 and 3, excluding -3 but including 3.

Side note: The range in interval notation is (-3, 3].
