Question

Prove that the remainder function is onto but not one-to-one

Answer 1

Answer:

An onto function is a function whose range is equal to its co-domain. To determine if the function is also not one-to-one, graph the function and imagine a series of lines perpendicular to the x-axis through the function. If the lines intersect the function at more than 1 point then it is not one-to-one.
