Question

F is a one-to-one function, and (4,7) is on the graph of f. Write the coordinates of a

known point or the graph of f-1
Format

Answer 1

(7, 4)

Explanation:

One-to-one function means that for every value of y in the range there is associated only one value in x in the domain.

If the point (x, y) belongs to f(x), then point (y, x) belongs to f^-1(x) (its inverse). In this case, (4,7) is on the graph of f(x), therefore (7, 4) is on the graph of f^-1(x)
