The inverse function of f(x) tells you what value of x you get for a given value of y. When you flip the graph about the 45 degree y=x line, it is the same as using the value of y on the original f(x) graph to get the value of x. In the flipped graph, what was formerly the y value is measured along the horizontal axis.
