Answer:

Step-by-step explanation:

Let us explain how to find altitude (amplitude), period, altitude interval, domain interval,phase shift and vertical shift

Altitude is the coefficient of cos or sin given

Period is the value got by dividing 2pi with coefficient of x

Altitude interval is given by (-a,a) where a is the coefficient of cos or sin

Domain interval is all real values for sin and cos

Phase shift is nothing but horizontal shift ie shift of x

Vertical shift is vertically up or down i.e. shift of y

Keeping those in mind we get

Q.No Altitude period altitude interval  domain interval  phase shift  vertical shift.
