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

It is c

Explanation:

edge

Answer 2

(C). y = 2sin( 8x -
`(4)/(3)` )

Explanation:

y = a sin k ( x - b )

a = 2 , k = 2π ÷
`(\pi )/(4)` = 8 , b =
`(1)/(6)`

8 ( x -
`(1)/(6)` ) = 8x -
`(4)/(3)`

y = 2sin(8x -
`(4)/(3)`)

(C). y = 2sin( 8x -
`(4)/(3)` )
