1.
Determine whether the function rule models discrete or continuous data.
A movie store sells DVDs for $15 each. The function C(d) = 15d relates the total cost of movies to the number purchased d.
A movie store sells DVDs for $15 each. The function C(d) = 15d relates the total cost of movies to the number purchased d.
a)
discrete
b)
continuous
2.
Tell whether the relationship should be represented by a continuous or discrete graph. Explain.
the height of a tree over time
the height of a tree over time
a)
Continuous; a tree grows gradually, not in steps, so this situation is continuous.
b)
Continuous; a tree grows in steps, so this situation is continuous.
c)
Discrete; a tree stops growing at a certain age, so this situation is discrete.
d)
Discrete; a tree never stops growing, so this situation is discrete.
3.
Tell whether the relationship should be represented by a continuous or discrete graph. Explain.
The money raised from a raffle with a $200 prize where the tickets cost $2.50 per person.
The money raised from a raffle with a $200 prize where the tickets cost $2.50 per person.
a)
Continuous; the money raised depends on the number of tickets sold, and since any number of tickets can be sold, this situation is continuous.
b)
Discrete; the money raised depends on the number of tickets sold, and since only a whole number of tickets can be sold, this situation is discrete.
c)
Continuous; the money raised depends on the number of tickets sold, and since a person can buy more than one ticket, this situation is continuous.
d)
Discrete; the $200 prize is a whole number, so the situation is discrete.
4.
Which equation matches the table?
a)
y = x + 5
b)
y = 5x
c)
y = x - 5
d)
x = y - 5
5.
Find the function rule.
a)
y = 2x
b)
y = 2x+3
c)
y = 3x+3
d)
y = 2x+3
6.
Identify the function rule that best represents the following statement:
The total cost (C) for kilograms of beef (k) if each kilogram costs $2.55
The total cost (C) for kilograms of beef (k) if each kilogram costs $2.55
a)
C = 2.55k
b)
C = 2.55 + k
c)
C = 2.55 - k
d)
C = 2.55k + 2.55
7.

y = 2x + 4
a)
b)
c)
d)
8.

(-3, 8) (-1, 4) (0, 2) (8, -14)
a)
y = -5x + 3
b)
y = -3x - 1
c)
y = -2x + 2
d)
y = -4x - 4
