Question

How do you graph `y=sin(x-pi)-1`?

Answer 1

Take the original sin function
Shift to the right `π`
Shift down 1

The original function is `y=sin(x-(x:translation)) + (y:translation)`
With a horizontal shift of x units to the right and y units up.

Because this function is `y=sin(x-pi)-1`

We shift `pi` units to the right
And `-1` units up or `1` unit down
