Question

Please Help! Determine the range of the following graph:

Answer 1

• - 4 ≤ y ≤ 2 or [ -4; 2 ]

Explanation:

The range of the function is the set of all y- values.

The range on the graph can be determined by minimum and maximum points if the graph is continuous.

Looking at the given graph we observe:

• The minimum is y = - 4,
• The maximum is y = 2,
• The graph is continuous between these two points.

The range is:

• - 4 ≤ y ≤ 2 or
• [ -4; 2 ]
