Question

For the function f(x)=-2sin(4x-pi), in naming the variables, would D=0?

Answer 1

D being the horizontal shift?
Like from this form?\[\Large\rm y=A \sin(B(x-C))+D\]
Yes D=0
:)

Answer 2

I also have:
A=-2
B=4
C=pi?

Answer 3

I mean vertical shift :3 blah sorry.

Answer 4

Umm I guess it depends how you're defining your horizontal shift.
The horizontal shift is with the coefficient on the x pulled out first.
But yes I still think we call it C, because we define our horizontal shift to be C/B.

Ya ya ya ok ok ok, ignore my rambling.
Yessss those values look correct \c:/ good job!

Answer 5

Okay!!! Thank you so much! Just wanted to double check.

Answer 6

Expanding on this, I have:

Amplitude=-2
Period=pi/2
Phase shift=pi/4
Right end point=3pi/4?
