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=​

See below for answers

Step-by-step explanation:

Do you mean or ?

Use the formula where is the amplitude, is the phase shift, is the vertical shift, and the period is .

Assuming your first case is true, the amplitude would be , your period is , and your midline/vertical shift is .

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

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
