Question

Which table represents the inverse of the function defined above?

Answer 1

Hello!

Answer:

Table B.

Step-by-step explanation:

An inverse of a function means that the x and y values are swapped in comparison to the original function. For example:

We can use points on the table:

$f(x)$ = (7, 21)

The inverse of this function would 7 as its y value, and 21 as its x value:

$f^{-1} (x)$ = (21, 7)

The only table shown that correctly shows this relationship is table B.
