Graphing

100

What is the amplitude of this equation?

Y=4cos2x

Answer: 4

200

What is the phase shift of this equation?

y=3sin(x-2)

The Phase shift is none. If you were to move anything at all, it would be a vertical shift of 2.

300

A tangent function has an amplitude of 3, period of π, a transformation of π/2 to the right, and a transformation down 1. What is the equation for this trigonometric function?

y=3tan(x-π/2)-1

400

Graph the following equation.

y=3tan(x + π/2)−2

500

Give me the amplitude, phase shift & vertical shift. 

y= 1/2 ⋅tan(x − π/2)+1

Amp:1/2

Vert: Up 1 

Phase: Right π/2
