Chapter 8.2, Problem 22E

To determine

To graph:

The given equations. Tell whether each equation is a function.

Answer to Problem 22E

The equation $x=3$ is not a function.

Explanation of Solution

Given:

An equation: $x=3$

Calculation:

Upon graphing $x=3$ , we will get our required graph as shown below:

We can see that the graph of line $x=3$ is a vertical line, so one value of x corresponds to infinitely many y- values. Therefore, the equation $x=3$ is not a function.
