It creates dogx^2 and then flip your answer and multiply by 2

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.

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85

Write checks carefully, keep and accurate record of checks, and deposits made.
