WebExample 1: f (x) = 2x Is Onto for f: R → R. The function f (x) = 2x is onto when we consider its domain (all real numbers) and codomain (all real numbers). This is easy to see: for any real number y, we simply divide by 2 to get x: x = y/2. This value of x will map to the desired value of y. WebIn order to prove the given function as onto, we must satisfy the condition. Co-domain of the function = range. Since the given question does not satisfy the above condition, it is not onto.
