WebTherefore f (x) = y To determine that whether the function f (x) is a One to One function or not, we have two tests. 1) Horizontal Line testing: If the graph of f (x) passes through a unique value of y every time, then the function is said to be one to one function. For example Let f (x) = x 3 + 1 and g (x) = x 2 - 1 WebThe most common graphs name the input value x x and the output value y y, and we say y y is a function of x x, or y = f (x) y = f ( x) when the function is named f f.
