The inverse of F(x) is a function

Step-by-step explanation:

Let f be a function having domain in the set X, and range in the set Y. Then f would be invertible if there exists a function g having domain Y and range X, such as:

In other words, the function is applied to an input x, and gives an outcome of y, then its inverse function, let say , can be applied to y to give the result of x.

In other words,

y = f(x) if and only if x = g(y)

For example, considering the function

the inverse is:

the answer is: the length is 5/6 yards.
