Multiple Representations of Function
How much would it
cost for 2 friends?
How much would it
cost for 3 friends?
How much would it
cost for 4 friends?
The ordered pairs are on a line.
Multiple Representations of Function
Objective: Construct and analyze different
verbal, graphical and algebraic
representations of functions.
Multiple Representations of Function
Words and equations can be used to describe
functions. For example, when a rate is
expressed in words, it can be written as an
equation with variables. When you write an
equation, determine what variables to use to
represent different quantities.
Multiple Representations of Function
A runner’s distance in a marathon is equal to 8
miles per hour times the number of hours.
Let d = distance, t = time
d = 8t
Multiple Representations of Function
The drama club is holding a bake sale. They
are charging $5 for each pie they sell. Write
an equation to find the total amount earned t
for selling p pies.

The drama club is holding a bake sale. They
are charging $5 for each pie they sell. Write
an equation to find the total amount earned t
for selling p pies.
Let t = total money earned, p = number of pies
sold
t = 5p

In a science report, Mia finds the average
adult breathes 14 tines each minute when not
active. Write an equation to find the total
breaths b a non-active person takes in m
minutes.
Do this on your own.

While in normal flight, a bald eagle flies at an average
speed of 30 miles per hour. Make a function table
and write an equation to describe the relationship
between the total distance d a bald eagle can fly in
h hours. Then graph the ordered pairs.

An African elephant eats 400 pounds of vegetation each
day. Write an equation to represent the number of
pounds of vegetation (v) an African elephant eats in (d)
days. Graph the ordered pairs. How much will an African
elephant eat in one week?

An African elephant eats 400 pounds of vegetation each
day. Write an equation to represent the number of
pounds of vegetation (v) an African elephant eats in (d)
days. Graph the ordered pairs. How much will an African
elephant eat in one week?
v = 400d
If d = 7,
v = 400 · 7
= 2800
Multiple Representations of Function
Board 4 U charges $10 per hour to rent a
snowboard while Slopes charges $12 per hour.
Will the cost to rent snowboards at each place
ever be the same after zero hours?

Board 4 U charges $10 per hour to rent a
snowboard while Slopes charges $12 per hour.
Will the cost to rent snowboards at each place
ever be the same after zero hours?
No
Boards 4 U ; y = 10x
Slopes; y = 12x
There is no value for x (after zero) in which y would
be the same.
