Question

Write a function rule for “The output is 5 less than four times the input.” Use x for the independent variable and y for the dependent variable.

Answer 1

y(x) = 4x - 5

Explanation:

A dependent variable depends on other factors that are measured . The value of a dependent variable depends on the independent variable. The independent variable stands alone and it does change by the other variable you are trying to measure. Independent variable are usually denoted as x.

The function can be represented below.

y(x) = 4x - 5

x = independent variable

y = dependent variable

y depends on the value of x
