Question

f (x) = x is inverse function on integer number?​

Answer 1

Answer:

Step-by-step explanation:

f(x) = x2 and g(x) =

f(2) = 22 = 4 and g(4) = √4 = 2

f(g(a)) = = a

g(f(a)) = = a

It doesn't matter which of the two functions f(x) or g(x) we apply first, the result is the same. The range of one fuction becomes the domain of the other.

A function has an inverse only if it is one - to - one and onto. In this case we limit our values of x to non negative numbers so that the function f(x) = x2 satisfies this condition. In other words a function has an inverse if it is increasing or decreasing on it's domain. The function g(x) = √x is increasing and can only take non - negative numbers which again means that f(x) = x2 is limited to non - negative numbers.

We can find the equation of an inverse function algebraically by solving the equation of the function for
