![]() One-to-one mapping is called injection (or injective). ![]() Graphically, if a line parallel to x axis cuts the graph of f(x) at more than one point then f(x) is many-to-one function and if a line parallel to y-axis cuts the graph at more than one place, then it is not a function. While x → x 2, x ε R is many-to-one function. no two elements of A have the same image in B), then f is said to be one-one function. If for each x ε A there exist only one image y ε B and each y ε B has a unique pre-image x ε A (i.e. Consider the function x → f(x) = y with the domain A and co-domain B.
