Question 527499
A function is a relation that maps a set of inputs, or the domain, to the set of outputs, or the range. Note that for a function, one input cannot map to more than one output, but one output may be mapped to more than one input.


I'll have you try to construct a function and "non-function" that satisfies the conditions. The sentence you typed "This is extremely important for your learning" is not necessary because tutors on algebra.com already know what functions are. Just specify some inputs and outputs (they can be random -- it does not have to be linear, quadratic, etc.), and make sure that you follow the guidelines on whether a relation is a function.
