Jess has 4y + 2 lollipops and Maddy has hy - 4 lollipops. Write an expression in simplest form to show how many lollipops Jess and Maddy have in total. Find the total number of lollipops if y = 2.
Incorrect Work Solution
(4y + 2) + (6y - 4)
= 10y - 2
= 8y
=8(2)
=16

I’m pretty sure the answer is a

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.
