Question

Given the graph below state whether or not the relation is a function, and give the domain and

Answer 1

Answer:

• NOT a function
• domain: [-2, 2]
• range: [-4, 4]

Step-by-step explanation:

A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.

The domain is the horizontal extent, which is from -2 to +2.

The range is the vertical extent, which is -4 to +4.
