Plz help/ Trigonometric models and sine functions: plz show how you got and the GRAPH! Thx to anyone that can help

Answer:

$y=-2\sin(2x)-2$ - The graph is attached below.

Step-by-step explanation:

Given : A sine function has the following key features:

Period = π , Amplitude = 2, Midline: y = -2 , y-intercept: (0,-2)

The function is a reflection of its parent function over the x-axis.

To plot the graph :

Solution :

General form of sin function is $y=A sin(Bx)+C$

Where A is the amplitude

$B=\frac{2\pi}{\text{Period}}$

C is the midline

Substitute the given key features

A=2 , C=-2

$B=\frac{2\pi}{\pi}=2$

The sin function is $y=2\sin(2x)-2$

The function is a reflection of its parent function over the x-axis.

i.e, The coordinate became (x,y)→(x,-y)

The sin function is $y=-2\sin(2x)-2$

Now, We plot the graph of the sin function.

The graph is attached below.

First point is midline i.e, (0,-2)

Minimum point is $(\frac{\pi}{4},-4)$

All you have to do it do 60 - 35 = 25 dollars because they want to know if the original price would be 60 dollars and they wanna know the anwser if you took away 35 dollars. so then you just subtract
