On his last history test, marty only missed one question. he received -3 points for that question. his friend julie forgot to study and missed six questions. if each question was worth the same amount of points, how many points did julie receive for those six questions?

It appears that for every question missed, it deducts 3 points.

so if Julie missed 6 questions, then she received a : (-3 * 6) = -18

The answer is a good luck

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.
