Javier bought 48 sports cards at a yard sale. of the cards, 3/8 were baseball. how many cards were baseball cards ?

48 times 3/8
8units =48
1unit = 6
3units =18

No solution : there is no number of boxes that she bought

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.
