How do you find the period of a graph? How do you find the amplitude and period of this function: y=-3 sinx

    3 is the amplitude since its all out in front

    and the period is a normal sin period of 2pi

    isn't 2pi the period of sinx?

    So I am still confused on how to find the period of the graph?

    sin(x) is nekkid so you just use its normal period; its normal cycle time of 2pi

    sin(2x) means that the period is twice as fast and only take 1/2 the time to make a complete cycle; sin(2x) has a period of 2pi/2 = pi

    sin(pi x) has a period of 2pi/pi = 2
