CEVAP:

The matching of the sets {a, b, c, d } and {1, 2, 3, 4} thus obtained is a function which we call as the inverse function of h. Consequently, having a oneto-one and onto function, it is possible to define a new function by reversing the directions of the arrows as we did in the preceding examples. This newly constructed function is called the inverse of the given function. Mathematically put: Let the bijective function f : A›B be given. The inverse of f is defined as
f –1:B›A, f –1(y)=x
