What is the domain of this function?

Option A

Step-by-step explanation:

A domain of a function are all the inputs of the function. (or x-values)

The picture is a function mapping.

The left 'oval' contains the domain, as the right 'oval' contains the range.

The numbers in the left oval are [-1,3,5]. Therefore, they are the domain of the function.

Option A should be your correct answer.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
