Is it possible to create a function that has two values of y for every one value of x, or is this an unbreakable rule of functions?

Functions are mathematical relationships between two or more variables, where one variable (known as the independent variable) affects the value of another variable (known as the dependent variable). Functions are commonly represented as y = f(x), where y is the dependent variable and x is the independent variable.
This means that the function is not a one-to-one relationship, and the same value of the independent variable (x) can result in multiple values of the dependent variable (y). This is known as a many-to-one function.
Yes, this is known as a one-to-many function, where different values of the independent variable (x) can produce the same value of the dependent variable (y). This is also known as a non-injective function.
A one-to-one function is a relationship where each value of the independent variable (x) has a unique value of the dependent variable (y). This means that no two different values of x can produce the same value of y. In contrast, a many-to-one function can have multiple values of y for the same value of x.
The easiest way to determine if a function is one-to-one or many-to-one is by graphing it. If the graph passes the horizontal line test (no horizontal line intersects the graph more than once), then the function is one-to-one. If the graph fails the horizontal line test, then it is many-to-one.
