The fee for ride tickets at a carnival is shown in the
table at the right
a. Is the fee for ride tickets
proportional to the number of
tickets? Explain your reasoning.

b. Can you determine the fee for 30 ride tickets? Explain.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
