Consider the following examples in real-world situations that describe a correspondence between phenomena:

• The income tax a person pays depends on the person’s total income
• The number of years of experience on a job has a direct bearing on the salary received. The amount by which your savings will grow in a year depends on the interest offered by the bank.
• The area of a circle depends on the radius of the circle.
• The distance travelled in a car at a certain rate depends on the time travelled.



a) Express each situation in functional words. For example, the income tax is a function of the total income.
b) For each situation, indicate the dependent and independent variable.
c) Write the two variables as an ordered pair, and write the function using the notation
