Pls !
a sine function has the following key features:
period = 4π
amplitude = 3
midline: y = 2
y-intercept: (0,2)
the function is a reflection of its parent function over the x-axis.
use the sine tool to graph the function. the first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.

The sin function is

Step-by-step explanation:

Given :

A sine function has the following key features:

Period = 4π

Amplitude = 3

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

Where A is the amplitude

C is the midline  

Substitute the given key features

A=3 , C=2

The sin function is  

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

Now, We plot the graph of the sin function.

The graph is attached below.

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

Maximum point is

Minimum point is

333333333333333333333333333333

step-by-step explanation:

1 is c

2 is a

3 is a
