WebHere we have the function f(x) = 2x+3, written as a flow diagram: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2 . The inverse is usually shown by putting a little "-1" after the function name, like this: ... Injective, Surjective and Bijective Sets. Webf is injective if f (x)=f (y) IMPLIES x=y For example take f (x) = x^2 Suppose f (a) = f (b) Then, a^2 = b^2 But this does not imply a = b [ take a,b as 2, (-2) ] The point is that a function is injective if you can say for sure that if the function has the same value for two inputs than the the two inputs MUST be the same. 2 Quora User
