Which statements describes a many-to-one function?

A. It is a linear function

B. It passes the horizontal line test

C. It is a nonlinear function

D. Each x-value has more than one corresponding y-value

A many to one function would have to be a non linear function because for anything to share something else it could not go in a straight line. since it is a function we know that it passes the vertical line test but for it to not be linear, means it would not pass the horizontal line test. since it is not a linear function it would have to be non linear. and since it is a function and passes vertical line test each x value can only have 1 y value
