Investigating Sine

Change a = 3,  and d = 4. Y= 3sin x + 4 Does the amplitude of the function change? What stays the same? what else changes? What does it effect?

What is the range of the function y = 3 sin x +4

Change the sliders to y = sin 2x -3 (where b = 2 and d = -3) Does the period of the function change? If so, to what? Did the function move up or down?

What is the Range of the function y = sin 2x -3
