Write a function rule for "The output is 7 less than three times the input." Use x for the independent variable and y for the dependent variable. I need help

f(x) = 3x - 7

Step-by-step explanation:

Let the independent variable of a function is 'y' and dependent variable 'x'.

Therefore, function will be in the form of y = ax - b

Now statement given in the question states that "The output is 7 more than 3 times the input."

That means y is 7 less than 3 times of x.

y = 3x - 7

Rewrite this equation in the form of a function.

f(x) = 3x - 7
