Graph 1: Please help me sketch the graph of this equation. Please include: 1. the maximum and minimum
2. the midline
3. the period and rate constant
4. formula for the function
5. label the parts

 see answers below

Step-by-step explanation:

y = A cos (Bx - C) + D

Given: A = -3, B = π/20, C = 0, D = 5

1) midline (D) ± amplitude (A) = Max & Min

  Max: 5 + 3 = 8

  Min: 5 - 3 = 2

2) Midline (D) is given as 5

3) Period = 2π/B  = 2π/(π/20) = 40

4) Formula is given as: y = -3 cos (π/20)x + 5

5) change the coordinates of y = cos (x) and  as follows:

Note that A = -3, B = π/20, C = 0, D = 5

is only a line? i think so
