4 cards from this section. Quick, good the night before a test.
What is the amplitude of the function y = 5sin(x)?
Look at the coefficient of sin.
What is the period of y = sin(4x)?
Remember to divide 360° by B.
What does the A in the transformation y = A sin(Bx + C) + D represent?
Think about which value affects the height of the graph.
True or False: The period of a function increases as B increases.
Recall the formula for the period.
Given y = -4sin(2x + 30°) - 3, determine the amplitude, period, phase shift, and vertical shift. Sketch the function.
Start by extracting A, B, C, and D for the transformations.
Graph y = 3cos(0.5x - 90°) + 1, labeling the changes from the base cosine graph.
Carefully calculate each parameter before sketching!
