Thread: 1 trig problem please help

Equation: parent function (pre-image) is y=cos(x)

Equation: image function is y= -2 cos 3(x-π) + 5

π = pie

Explain how the graph of the image equation can be obtained from the graph of the parent function equation by applying the appropriate transformations?

Answer it yourself using the following...it will be much more satisfying

in the equation

the amplitude is



the period is

the phase shift is



and the d is a vertical shift up or down
