PLEASE HELPP I AM FAILING AND I NEED THIS ASAP!!! TYSM

Use the function f(x) = 2 sin x-1 to identify the following.

A. amplitude =
B. period =
C. midline=​

Answer 1

See below for answers

Explanation:

Do you mean
`f(x)=2sin(x-1)` or
`f(x)=2sin(x) -1`?

Use the formula
`f(x)=asin(bx+c)+d` where
`|a|` is the amplitude,
`-(c)/(b)` is the phase shift,
`d` is the vertical shift, and the period is
`(2\pi)/(|b|)`.

Assuming your first case is true, the amplitude would be
`|a|=|2|=2`, your period is
`(2\pi)/(|1|)=2\pi`, and your midline/vertical shift is
`d=0`.

Assuming your second case is true, everything but the vertical shift stays the same. It would be
`d=-1` in this case.
