Graphing Sine & Cosine (Amp, Vertical Shift, T)

what is the amplitude of
y = 3sin (7x) -2

• 7

• -2

• 3

• 6

The vertical stretch of the graph; distance between the midline and the max/min is called:

• Period

• Vertical Shift

• Phase Shift

• Amplitude

Assuming there is no phase shift, which function is this graph?

• y = sinx

• y = cosx

What is the period for y = sin x?

• 0

• 1

• $\frac{\pi}{2}$

• $\pi$

• $2\pi$

What is the period for y = cos x?

• 0

• 1

• $\frac{\pi}{2}$

• $\pi$

• $2\pi$

What is the period for y = cos 2x?

• 0

• 1

• $\frac{\pi}{2}$

• $\pi$

• $2\pi$

What is the equation of the graph?

•  y = 2 cos x

• y = sin x

• y = 2 sin x

• y = sin 2x
