Question

1. below is the mapping diagram of a relation:

does this relation represent a function?

a. yes

b. no

Explanation:

A function is a relation where each input (from the domain, left oval) has exactly one output (in the codomain, right oval). Here, the input \( 2 \) (in the left oval) maps to multiple outputs (\( -2, -1, 0, 1, 2 \)) in the right oval. Since one input has more than one output, this relation does not satisfy the definition of a function.

Answer:

B. No
