Question

For each graph below, state whether it represents a function.

Answer 1

Answer:

Step-by-step explanation:

A function is a relation in which each domain (X) value is paired with exactly one range (Y) value.

If, during the vertical line check, the vertical line intersect the graph of a relation once, then a relation is a function.

If, during the vertical line check, the vertical line intersect the graph of a relation twice, then a relation is not a function.
