What sine function represents an amplitude of 4, a period of , no horizontal shift, and a vertical shift of -3? (5 points)

f(x) = 4 sin x - 3

f(x) = -3 sin x + 4

f(x) = 4 sin 4x - 3

f(x) = -3 sin 4x + 4

Question

What sine function represents an amplitude of 4, a period of  , no horizontal shift, and a vertical shift of -3? (5 points)
 
f(x) = 4 sin  x - 3
 
f(x) = -3 sin  x + 4
 
f(x) = 4 sin 4x - 3
 
f(x) = -3 sin 4x + 4

amoodarya · Answer

amplitude of 4 is 4 sinx or 4 sin 4x
vertical shift -3 
choice 1,3

now if period is 2pi  sinx 
if period is pi/2  sin 4x
