Question

Write a function rule for "The output is 12 more than four times the input." Use x for the independent variable and y for the dependent variable. y=

Answer 1

f(y) = 12 + 4x

Explanation:

Output is 12 more than 4 timea the input

The dependent variable = y

The dependent variable = x

The input is the independent variable, x

Output is the dependent variable, y

Output = 12 + (4 * input)

Hence, the function rule can be written has :

f(y) = 12 + 4x
