if point (4, 5) is on the graph of a function, which equation must be true?\no f(5)=4\no f(5,4)=9\no f(4)=5\no f(5,4)=1
Answer
Explanation:
Step1: Recall function - point relationship
For a function (y = f(x)), if a point ((a,b)) lies on its graph, then when (x=a), (y = f(a)=b).
Step2: Identify (x) and (y) values of the given point
The given point is ((4,5)), where (x = 4) and (y=5).
Step3: Apply to function notation
Substituting (x = 4) into the function (y = f(x)), we get (f(4)=5).
Answer:
C. (f(4)=5)
