In other words, a function f is one-to-one if, for every a and b in its domain, f(a)=f(b) implies a=b.Inverse Function GraphThe graphs of f and f−1are symmetric over the line x=y. The functions f and f−1 are mirror images of each other on a graph since the roles ...
If the composition of two functions f(x), and g(x), results in an identity function f(g(x))= x, then the two functions are said to be inverses of each other. If the application of a function to x as input gives n output of y, then the application of another function g to y ...
Now that we can find the inverse of a function, we will explore the graphs of functions and their inverses. Let us return to the quadratic function f(x)=x2f(x)=x2 restricted to the domain [0,∞)[0,∞), on which this function is one-to-one, and graph it as in...
