Question

Determine if the following relations are1. {(1, -2), (-2, 0), (-1,2), (1,3)} Function:Domain: Range:

Answer 1

The relation is a function since for every x-values there is a y-value associated with it and moreover, every x-value has only one y-value associated with it.

The range of the function are the values of the x-variable, therefore, the ranges is:

`\text{RANGE}=\lbrace1,-2,-1,1\}`

The domain is the values of y, that is:

`\text{Domain}=\lbrace-2,0,2,3\}`
