The 2 doubles the amplitude (the height of the curve)
The +3 translates the whole curve up 3 units
The period tells you the space between repetitions of the curve.
When x = 0, y = 2 x 1 + 3 = 5
This next happens when pi/3 x = 2pi so x would = 6
The period of the curve = 6
2 grams
6 x 106 = 636
3 x 105 = 315
315 x (2) = about 630
400, because each interval represents 40 and they are 10 intervals apart. 40*10=400
Not sure if this is what you want but I multiply by the percent as a decimal
Answer:
T = -207
