You have 10 quarters that you can use for a parking meter.
a. Copy and complete: Each time you put 1 quarter in the meter, you have 1 less quarter, so ? is a function of ?
b. Write a rule for the number y of quarters that you have left as a function of the number x of quarters you have used so far. Identify the domain of the function.
c. Make a table and identify the range of the function.

a) "how many quarters you have is a function of how many times you paid for the parking meter."

b) y = 10 - x

domain: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

range: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

c) table:

x: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

y: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0

Here we know that you have a total of 10 quarters, and the parking meter costs 1 quarter.

Then, each time if we define two variables:

y = how many quarters you have.

x = how many times you paid for the parking meter.

We can write:

"y is a function of x"

Or:

"how many quarters you have is a function of how many times you paid for the parking meter."

b) The rule is really simple, it would be a linear relation:

y = 10 - x

The domain (the set of possible values of x) is:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

You can't use less than 0 quarters and you can't use more than 10.

c) The range is also:

{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Which represents the possible numbers of quarters that you can have.

And the table will be:

x: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

y: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
