You know that, If you draw a vertical line across the plot of the function, it only intersects the function once for each value of, Compare the previous graph with this one, which looks like a blue circle. A range is the set of all numbers that come out of the function (output). The quantity is given in C5. Some x-coordinates are repeated and have different y-coordinates. If there is more then one output for one input, then the relationship is not a function. The identity function on M is clearly an injective function as well as a surjective function, so it is also bijective. There are many kinds of relations. If a graph shows two or more intersections with a vertical line, then an input (x-coordinate) can have more than one output (y-coordinate), and y is not a function of x.
