1. a sine function has the following key features frequency = 1/4pi amplitude= 2 midline y= 2 y intercept (0,2) this function is not a reflection of its parent function of the x-axis 2. period 4 amplitude 3 midline y = -1 y intercept (0,-1) 3. period = pi amplitude = 2 midline y= -2 y intercept (0,-2)

1)

2)

3)

Step-by-step explanation:

General form of sin function is

Where A is Amplitude

B is

C is Mid line

1) Given : A sine function has the following key features  

Frequency =

Period is

Amplitude= 2

Mid line y= 2

Y intercept (0,2)  

This function is NOT a reflection of its parent function of the x-axis

Solution : We put the value in the general form of sin function

A= 2 ,   , C=2

2) Given : A sine function has the following key features  

Period = 4

Amplitude = 3

Mid line y = -1

Y intercept (0,-1)

Solution : We put the value in the general form of sin function

A= 3 ,   , C=-1

3) Given : A sine function has the following key features  

Period =

Amplitude = 2

Mid line y = -12

Y intercept (0,-2)

Solution : We put the value in the general form of sin function

A= 2 ,   , C=-2
