1. a surfer paddles out past breaking waves, rides a wave, paddles back out past the breaking
waves, rides another wave back to the beach. draw a sketch of a graph (with labels) that shows
the surfer's possible distance from the beach over time.
2. for the table, identify the independent and dependent variables, represent the relationship
using words, an equation and a graph. # of cases of bottled water, c# of bottles of waterb 1 24
2 48 5 120 10 240 20 480
3. sketch a graph of the function shown by the table. is its linear or nonlinear? x y 10 2 1 3 8 4
20
4. graph the function rule. use labels. explain why the graph is continuous or discrete. the
amount of money made by selling bikes depends on the number n of bikes sold. so a = 150n.
5. write a function rule to represent the situation: the volume, v, remaining in a 243 ft3 pile of
gravel decreases by .2 ft3 with each shovelful, s, of gravel spread in a walkway.
6. tell whether the relation is a function. explain your reasoning. {(-1,7), (9, 4), (3,-2), (5,3).
(9, 1);
7. tell whether the relation is a function. explain your reasoning.
8. describe the pattern in the sequence. find the next two terms of the difference. -2,-5, -8,
