Solution:
Suppose a function f has an inverse function, the graph of the inverse function will be a reflection of the graph of the function f about the line y=x.
Thus, given the graph of a one-to-one function as shown below:
The graph of its inverse function f⁻¹ will be a reflection of the above graph.
Hence, we have the graph of the inverse function f⁻¹ to be:
The correct option is A.
