If the graph is that of f(x), name a point that lies on f-1 (x).

Answer 1

If (x, y) lies on the graph of f(x), then (y,x) lies on the graph of \(f^{-1}(x)\)

Answer 2

That is one of the more interesting properties of sets of inverse functions.

Look at the graph. Identify the coordinates of any one point on this graph. Then reverse the order of the coefficients inside the parentheses: (x, y).

Answer 3

Yup, Just find a point on the curve, write it out as (x, y), then your inverse will just be that but switched as (y, x). Dont overthink it.

Answer 4

Thanks
