Answer:
y = 6+3x
Explanation:
If y = f(x), it means y is depending on x. This shows that y is the independent variable and x is the dependent variable.
y variable will be the output depending on the input variable x.
According to the function rule, “The output is 6 greater than three times the input." This can be expressed mathematically as 3x+6 (x being the input)
Three times the input = 3x
6 greater than three times the input = 6+3x
Since y is output then;
y = 6+3x
