Question

Is x = 1 a function?​

Answer 1

No, x = 1 is not a function

Explanation:

No, x = 1 is not a function. There's only one variable here. In a function or relationship, one variable maps onto another variable via some rule.

x = 1 can be graphed: It's a straight, vertical line. Recall that vertical lines have no defined slope.

Answer 2

No

Explanation:

A function is an equation for which any x value matches with exactly one y value .

x=1 matches with any y answer (as y is not included in the equation), so it is not a function.
