**Phase shift and sinusoidal curve fitting - Finding...**

## Homework Statement

*"Find the period, amplitude, and phase shift of each function. Graph each function. Be sure to label key points"*

**y = 4sin(2x - pi)**

## Homework Equations

## The Attempt at a Solution

So, I got...

Amplitude = 4

Period = 2pi/2 = 2

Phase shift: Would that be pheta/w ?, So pi/2 ?

__Now here is where I get messed up.__

I do not know how to get

**"Interval defining one cycle"**and

**"Subinterval width"**

**How do I generate points from this?**
