Question 753625
Write a sine function with the given amplitude, period, phase shift, and vertical shift.
amplitude: 2
period: {{{pi}}}
phase shift: {{{(-1/8)pi}}}
vertical shift: 3
***
Basic equation for sine function: y=Asin(Bx-C), A=amplitude, period=2π/B, phase shift(C/B) 
For given problem:
A=2
period=π=2π/B
B=2
phase shift=C/B
π/8=C/2
C=π/4
Equation:
y=2sin(2x+π/4)+3
