Question

What’s the amplitude,period,equation of axis, and range for y=3sin[2(x+90)]?

Answer 1

Answer:

• amplitude: 3
• period: π
• axis: y = 0
• range: [-3, +3]

Step-by-step explanation:

The amplitude is the multiplier of the sine function: 3.

The period is 2π divided by the coefficient of x: 2π/2 = π.

The equation of the axis is any added constant: y = 0.

The range is the axis value ± the amplitude value: from -3 to +3.
