Question

Write an equation for a sine curve that has the given amplitude and period, and which passes through the given point.
Amplitude 2, period pi/4, point (1/6,0)

Answer 1

Answer:

(C). y = 2sin( 8x - $\frac{4}{3}$ )

Step-by-step explanation:

y = a sin k ( x - b )

a = 2 , k = 2π ÷ $\frac{\pi }{4}$ = 8 , b = $\frac{1}{6}$

8 ( x - $\frac{1}{6}$ ) = 8x - $\frac{4}{3}$

y = 2sin(8x - $\frac{4}{3}$)

(C). y = 2sin( 8x - $\frac{4}{3}$ )
