Investigating the Cosine Curve
Which letter effects the amplitude?
How does the b value change the graph? When it is less then 1? When it is greater then 1? try b = 1/2 and b = 5, describe how the curve changes.
How does the d value effect the graph. Try y = cos x +2. What happens? Amp? period?
Graph y = 2 cos x +4 State the amplitude, period, and vertical shift
What is the range of the function y = 2 cos x +4
Graph y = -3 cos 2x -1 Amp? Period? Vertical Shift?
Range of y = -3 cos 2x -1
