If point (4, 5) is on the graph of a function, which equation must be true? f(5)=4 f(5,4)=9 f(4)=5 f(5,4)=1

 The correct option is (C)

Step-by-step explanation:  Given that a point (4, 5) lies o the graph of a function.

We are to select the equation that must be true.

We know that

if a point (a, b) lies on the graph of a function y = f(x), then we write the equation as follows :

Therefore, if the point (4, 5) lies ob the graph of function y = f(x), the the equation is

Thus, the required equation that is TRUE is

Option (C) is CORRECT.
