One output for each input
U can see if there is and input that can go into two outputs if there is it's not a function if there is and imput that only goes in to one output it's is a function
A linear function has and x and a y and neither one is raised to a power other than 1.
One way is to try the vertical line test on a graph!
You need to know the domain in order to find the range.
See the related link - Math Warehouse.First it has to be a function, that means for each and every x value, there is one and only one y value. Often the term vertical line test, is used. That means a vertical line will cross the graph only one time at every x value, then it is a function.If it is a function, and for every y-value, there is only one x-value, then it is a one-to-one function. Often you may see horizontal line test, as a way of checking.Examples of one-to-one functions:y = xy = 2x +3y = e^xExamples of functions, which are notone-to-one:y = x² [parabola: (2)² and (-2)² both equal 4]y = sin(x) [y will oscillate back and forth between +1 and -1 indefinitely]If a function passes the tests and is a one-to-one, then the function will have an inverse.Also, a function can be defined as one-to-one over a specific range. Like x² for all x > 0 {positive numbers}
The basic function of eye is to see the thing around us.
to see or to view one's image

By definition. If one input has more than one outputs then it is not a function.
I think the song you are referring to may be "I Know a Heartache When I See One" by Jennifer Warnes.

isdigit is an example (see in ctype.h)
A differentiable function, possibly - to distinguish it from one whose graph is a kinked curve.
