7/8 tsps. is 1/4 groups of what size

Let, the teaspoons = x

x * 1/4 = 7/8
x = 7/8 * 4 = 7/2

Hope I helped! ( Smiles )

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.
