Question

Find the amplitude of y = -4 sin x.

Answer 1

In general

y = A*sin(Bx-C) + D

has an amplitude of |A|

Answer 2

y = A*sin(Bx-C) + D

|A| is the amplitude
T = 2pi/B is the period
C/B is the phase shift
y = D is the midline

Answer 3

so the answer is 4?

Answer 4

correct

Answer 5

okay thank you!
