Question

PLEASE HELP!!!!!!!!!!!!

Answer 1

This is your generic run-of-the-mill sinusoidal function:

f(x) = sin(x)

This is the same sine function but with a phase shift of 3 units to the right:

f(x) = sin(x-3)

This is the sine function but with an amplitude of 4 units:

f(x)  = 4sin(x)

This is the sine function but flipped across the x-axis:

f(x) = -sin(x)

Combine all these transformations to get:

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