1. Scientists estimate the rate of the wildebeest running at full speed to be 66 feet per second. Write a function rule to describe the relationship between the time, t, and the distance ,d, a wildebeest travels when running at full speed.(1 point)
a. t = 66d
b. 66 = d • t
c. d = 66/t
d. d = 66t
2. Identify the function rule shown in the table. (1 point)
n 3 4 5 6
y 2 1 0 -1
a. y = 2 + n
b. y = 5n
c. y = 5 - n
d. not enough information
3. Rico made a function table to illustrate the rate he charges for mowing lawns. Complete the table. Then write a function rule for the function. (1 point) ( ) = blank
Hours (h) 1 2 3 4 5
Earnings (E) ( ) ( ) ( ) $22.00 $27.50
a. $5.75, $11.50, $17.25; E = 5.75h
b. $6.00, $12.00, $18.00; E = 6.00h
c. $5.25, $10.50, $15.75; E = 5.25h
d. $5.50, $11.00, $16.50; E = 5.50h
4. A DVD store charges $4.70 for each day, d, a DVD is rented. The store also gives you a dollar off if the DVD is returned before 5 days.
1. Write a rule to represent the rental charges C.
2. How much will you pay if you return the DVD after 4 days? 7 days?
a. c = 4.70d; $18.00, $32.90
b. if d ≤ 5 then c = 4.70d, if d > 5 then C = 4.70d + 1; $17.80, $31.90
c. if d ≥ 5 then C = 4.70, if d < 5 then C = 4.70d - 1; $17.80, $32.90
d. if d ≤ then C = 4.70d, if d > 5 then C = 4.70d - 1; 18.80, $31.90
5. Write a rule for the function represented by the table. (1 point)
Input (x) 0 1 2 3 4
Output (y) 3 6 9 12 15
a. y = 3x
b. y = 3x + 3
c. y = 5x + 1
d. y = x + 5
6. (I know the answer)
7. Use the function rule to complete the table -10x + y = 4 (3 points)
( ) = blank
x -2 -1 0 1 2
y ( ) ( ) ( ) ( ) ( )
