Judy needs 514 quarts of oil to change the oil in her car. She has 212 quarts in one bottle and 114 quarts in another. How many more quarts of oil does Judy need to change the oil in her car?

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.
