Chapter 8: Q19. (page 410)

Graph the equation. Tell whether the equation is a function.
$x = - 4$

Short Answer

Expert verified

The equation $x = - 4$ is not a function.

Step by step solution

Step 1. Given information.

The given equation is $x = - 4$ .

Step 2. Calculation.

Upon graphing $x = - 4$ , we will get our required graph as shown below:

We can see that the graph of line $x = - 4$ is a vertical line, so one value of x corresponds to infinitely many y-values. Therefore, the equation $x = - 4$ is not a function.

Therefore, the equation $x = - 4$ is not a function.

Step 3. Conclusion.

The given equation is not a function.
