Answer: y = -10 sin (πx) + 4
<u>Step-by-step explanation:</u>
y = A sin (Bx - C) + D
- Amplitude: A
- Period = 2π/B ---> B = 2π/Period
- Phase Shift = C/B --> C = B · Phase Shift
- D: midline, vertical shift
Given:
- A = 10
- B = 2π/2 = π
- C = B · 0 = 0
- D = 4
- reflection over x- axis
Equation:
y = -10 sin (πx - 0) + 4
10:4, 15:6, and 20:8. All you do is add the original ratio to its self
