If (-9, 2) is on the graph of flx), which point must be on the graph of the
inverse function f-1(x)?

(2, - 9 )

Step-by-step explanation:

Since 2 is the output when - 9 is input to f(x)

Then reversing the procedure, that is the inverse gives an output of - 9 for an input of 2.

(- 9, 2) is a point on the graph of f(x), then

(2, - 9) is a point on the graph o the inverse function (x)

you would need to know all the numbers that are on there
