To find: The graph of the equation, thedomain and range of the given relation, and whether the given relation is a function.

Answer to Problem 17PPS
The domain of the given relation is all the real numbers and the range of the given relation is all the positive real numbers.
Explanation of Solution
Given information:
The given equation is,
Consider the graph of the given equation,
The domain of the given relation is all the real numbers and the range of the given relation is all the positive real numbers.
A relation is said to be a function if x -co-ordinate is paired with exactly one y -co-ordinate. In this relation, so the given relation is a function.
Each element of the range is paired with the unique element of the domain, so it is a onto function.
Hence, the given relation is a onto function.
From the graph, it is clear that the given equation is discrete.
