Question
What does a vertical line on desmos mean
Answers
GPT-4o mini
In Desmos, a vertical line represents a function or relationship where the x-coordinate remains constant while the y-coordinate can take any value. This means that for each point on the vertical line, the x-value is the same, but y can vary from negative to positive infinity.
Mathematically, a vertical line can be expressed in the form \( x = a \), where \( a \) is a constant. For example, the equation \( x = 3 \) describes a vertical line that crosses the x-axis at \( x = 3 \).
However, it's important to note that a vertical line does not represent a function in the traditional sense because it fails the vertical line test: for a given x-value, there are multiple corresponding y-values, which violates the definition of a function that allows only one output for each input.
