A function is a black box, with a funnel to put numbers in, a chute where numbers come out, a crank on the side, and some machinery inside.
You put a number in, turn the crank, and a number comes out ... usually different from the one you put it.
If you do that enough times with enough different numbers, you can figure out what machinery is inside.
Or, if you know what the machinery is, then when you put a number in, you can always predict what number will come out.
A function is a specific relationship where each input is linked to exactly one output. It can be represented mathematically, such as with the equation y = 2 x + 3 . Graphically, functions can be checked using the vertical line test to ensure each input corresponds to one output.
