one value for "Y" for every "X" is related by a function... it cannot be a function if it has more than one Y value for an X value
A function relationship between two or more variables, inputs and outputs, where each and every value input has a uniqueoutput.
Assuming that y is a function of x, that follows from the definition of a function. For each x-value, there can only be one y-value. The definition of a function is that (in this case), for every value of "x", a value of "y" can be calculated unambiguously. In the more general case, for every combination of the independent variables, a single value for the dependent variable can be calculated unambiguously.
No. One argument of function may have only one value. So, if it has more than one value, it is not a function.
A piecewise function is a function defined by two or more equations. A step functions is a piecewise function defined by a constant value over each part of its domain. You can write absolute value functions and step functions as piecewise functions so they're easier to graph.

No. A function must have no more than 1 y-value for each x-value. A vertical line has an infinite number of y-values at a single x-value.
A function relationship between two or more variables, inputs and outputs, where each and every value input has a uniqueoutput.
A function is a relationship between x and y-values in which each x value has one and only one corresponding y value (note that y-values are allowed to have more than one corresponding x-value).
A function assigns each value of the depend variable to more than one value of the inde variable is this true or false

The function of x exists when there is only one answer for each value of x. Like y=2x+1. It is not a function if there are two or more answers for an x value like x=y^2 (x equals y squared)
