A sine function has the following key features:

Period = 4

Amplitude = 4

Midline: y = 1

y-intercept: (0, 1)

The function is not a reflection of its parent function over the x-axis.

Similar to the others, here is the graph:  cheeky

We have the form

 

y = Asin (Bx + C) + D

 

A = the amplitude = 4

 

To compute "B"  we have

 

B =  2pi / period    =   2 pi / 4   =    pi /2

 

C = phase shift    (none)  so    C = 0

 

D = midline  =  1

 

So.......we have

 

y =  4 sin (  pi/2 * x ) + 1

 

 

cool cool cool
