Question
For the linear function f ,the table above gives some values of x and their corresponding values f (x), where c is a constant. Which of the following equations defines f?
- f(x) =x + c
- f(x)=x + 3c
- f(x) = cx + c
- f(x) = 3cx + 3c
The correct answer is: f(x) = cx + c
The points the linear function f passes is (0, C) & (1, 2C)
The line equation is 
y - c = cx
y = cx + c
