2. 1. If a rabbit can run 3 feet per second, how
long will it take to run 105 feet?
2. What number is halfway between 3 and -7?
3. The cost of a car rental increases from $50
to

4. Calculate 3/7 of 28
5. How long does it take a car to travel 150
miles at 60 miles per hour?
6. How many three-quarter pizzas are there
in 6 pizzas?

3. Functions that can be written as equations
can be written in function notation. The
variable y and the term f(x) represent the
dependent variable. It is simply a way to
show that the y variable is a function
of, or depends on x. It is read "f at x"
Since x can be any number, the f(x) is the
output, (the dependent variable), when a
number is substituted for x.
Example:
Let's look again at our original phone call
equation, and rewrite it again in function
notation.
