What are the amplitude, period, and phase shift of the given function?

The correct choice is B.

Step-by-step explanation:

The given function is

The given function is of the form;

where

is the amplitude.

The period is calculated using the formula;

The phase shift is given by;

The correct choice is B

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
