if point (4, 5) is on the graph of a function, which equation must be true?\n○ f(5)=4\n○ f(5,4)=9\n○ f(4)=5\n○ f(5,4)=1
Answer
Explanation:
Step1: Recall function - point relationship
For a function (y = f(x)), if the point ((a,b)) is on the graph of the function, then when (x=a), (y = f(a)=b).
Step2: Identify (x) and (y) values
Given the point ((4,5)), here (x = 4) and (y = 5). So (f(4)=5).
Answer:
C. (f(4)=5)
