Let's consider the given function. In the above formula, is the number of cylinders Ralph has left after finishing his work on engines. Since the number of cylinders remaining, depends on the number of motors, we can say that is the dependent variable and is the independent variable.
To determine the range of the function, we can substitute the given domain values into the equation and simplify.
From the table above, we can identify the -values in the range that correspond to the -values in the domain.
