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

Answer 1

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
