Question

question 4 of 10
f(x) is a function.
a. true
b. false

Explanation:

A function requires that each input (from the domain, left oval) has exactly one output (in the codomain, right oval). Here, each element 1, 2, 3, 5 in the domain maps to only one element in the codomain. So \( f(x) \) is a function.

Answer:

A. True
