1.  1. Given the functions g(x), f(x), and h(x) shown below:
The correct list of functions ordered from greatest to least by average rate of change over the
interval 0 ≤ x ≤ 3 is
(1) f(x), g(x), h(x)
(2) h(x), g(x), f(x)
(3) g(x), f(x), h(x)
(4) h(x), f(x), g(x)

  

2.  2. The graphs below represent functions defined by polynomials. For which function are the zeros
of the polynomials 2 and –3?

  

3.  3. For which function defined by a polynomial are the zeros of the polynomial –4 and –6?
(1) y = x^{2} − 10 x − 24
(2) y = x^{2} + 10 x + 24
(3) y = x^{2} + 10 x − 24
(4) y = x^{2} − 10 x + 24

  

4.  4. The length of the shortest side of a right triangle is 8 inches. The lengths of the other two sides
are represented by consecutive odd integers. Which equation could be used to find the lengths
of the other sides of the triangle?
(1) 8^{2} + (x + 1) = x^{2}
(2) x^{2} + 8^{2} = (x + 1)^{2}
(3) 8^{2} + (x + 2)^{2} = x^{2}
(4) x^{2} + 8^{2} = (x + 2)^{2}

  

5.  5. Donna wants to make trail mix made up of almonds, walnuts and raisins. She wants to mix one
part almonds, two parts walnuts, and three parts raisins. Almonds cost $12 per pound, walnuts
cost $9 per pound, and raisins cost $5 per pound.
Donna has $15 to spend on the trail mix. Determine how many pounds of trail mix she can
make. [Only an algebraic solution can receive full credit.]

  

6.  6. A high school drama club is putting on their annual theater production. There is a maximum of
800 tickets for the show. The costs of the tickets are $6 before the day of the show and $9 on
the day of the show. To meet the expenses of the show, the club must sell at least $5,000 worth
of tickets.
a) Write a system of inequalities that represent this situation.
b) The club sells 440 tickets before the day of the show. Is it possible to sell enough
additional tickets on the day of the show to at least meet the expenses of the show? Justify
your answer.

  

7.  7. During a snowstorm, a meteorologist tracks the amount of accumulating snow. For the first
three hours of the storm, the snow fell at a constant rate of one inch per hour. The storm then
stopped for two hours and then started again at a constant rate of onehalf inch per hour for the
next four hours.
a) On the grid below, draw and label a graph that models the accumulation of snow over time
using the data the meteorologist collected.
b) If the snowstorm started at 6 p.m., how much snow had accumulated by midnight?

  

8.  8. Next weekend Marnie wants to attend either carnival A or carnival B. Carnival A charges $6 for
admission and an additional $1.50 per ride. Carnival B charges $2.50 for admission and an
additional $2 per ride.
a) In function notation, write A(x) to represent the total cost of attending carnival A and
going on x rides. In function notation, write B(x) to represent the total cost of attending
carnival B and going on x rides.
b) Determine the number of rides Marnie can go on such that the total cost of attending each
carnival is the same. [Use of the set of axes below is optional.]
c) Marnie wants to go on five rides. Determine which carnival would have the lower total
cost. Justify your answer.
