Starter - Writing Trig Equations

The amplitude is:

• 6

• 8

• 4

• 12

The period is:

• $2\pi$

• $\pi$

• $\frac{\pi}{2}$
  

• 8

Since the period is  $\pi$  , that means the B-value is:

• $2\pi$

• 2

•  $\pi$  

• 4

The midline is:

• y=-4

• y=0

• y=2

• y=8

To get the simplest possible equation, I should use:

• sinx

• -cosx

• -sinx

• cosx

Given that A=6, B=2, the midline is y=2, and I should use cosine, what is the equation of the graph?

y=_____________________________________________
