which graph shows a function and its inverse?\na.\nb.\nc.

Explanation:

Step1: Recall property of function - inverse graphs

The graph of a function (y = f(x)) and its inverse (y = f^{-1}(x)) are symmetric about the line (y=x).

Step2: Analyze each option

In option A, the two lines are symmetric about the line (y = x) (the line with a slope of 1 passing through the origin). In option B and C, the graphs of the two - lines are not symmetric about the line (y=x).

Answer:

A.
