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

01

Step 1. Given information.

The given equation is x=-4.

02

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.

03

Step 3. Conclusion.

The given equation is not a function.
