If (4, -5) is on the graph of f(x), which point must be on the graph of the inverse function f -1(x)?
a. (5, -4)
b. (-4, 5)
c. (4, -5)
d. (-5, 4)

Option d is right.

Step-by-step explanation:

We know that a relation is a function only if every element in domain has a unique image.

A function has an inverse only if it is one to one and on to.

Here image is -5

Since one to one function, preimage is only 4

Hence inverse function will have ordered pair as

(-5,4)

Option d is right
