whats the period, range and amplitude of y=-3 cos 4x

OpenStudy (anonymous):

period is pi/2 amplitude is -3 range is -3 <= y <= 3 ( i think )

OpenStudy (anonymous):

I think the range is -3 to 3 since the range is just the min and max y values. No matter what number x is y will never be smaller than -3 or larger than 3.
