The answer is option A. As we can clearly see that f(x) is a dependent function and it’s dependent on an independent variable x

Answer:
Option A is correct .i.,e f(x) = 6x + 9
Step-by-step explanation:
Given Equation, y - 6x - 9 = 0
We have to write given equation in function notation with x as independent variable.
To find a function with x as independent variable we must express the given equation in terms of x.
Consider,
y - 6x - 9 = 0
transpose 9 to RHS
y - 6x = 0 + 9
y - 6x = 9
transpose 6x to RHS
y = 9 + 6x
f(x) = 6x + 9
So, Option A is correct .i.,e f(x) = 6x + 9
