Chapter 4.2, Problem 19E

Concept Check Match each function in Column I with the appropriate description in Column II.

II

A. amplitude = 2, period = $\frac{\pi }{2}$, phase shift = $\frac{3}{4}$

B. amplitude = 3, period = $\pi$, phase shift = 2

C. amplitude = 4, period = $\frac{2\pi }{3}$, phase shift = $\frac{2}{3}$

D. amplitude = 2, period = $\frac{2\pi }{3}$, phase shift = $\frac{4}{3}$

I

y = 3 sin (2x – 4)
