Answer: Â y = -10 sin (Ï€x) + 4
Step-by-step explanation:
y = A sin (Bx - C) + D
- Amplitude: A
- Period = 2Ï€/B Â Â ---> Â Â B = 2Ï€/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
The equation of the function should be  y = -10 sin (πx) + 4.
Calculation of the equation:
Since
y = A sin (Bx - C) + D
Here
Amplitude: A
Period = 2Ï€/B Â Â ---> Â Â B = 2Ï€/Period
Phase Shift = C/B  --> C = B · Phase Shift
D: midline, vertical shift
Also, it is mentioned that
A = 10
B = 2π/2 = π
C = B · 0 = 0
D = 4
reflection over x- axis
So, here the equation is y = -10 sin (Ï€x - 0) + 4
