Answer:
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.
6 2 2pi (-2,2) (-infty,infty) pi/3 right 0
7 1/3 2pi/3 (-1/3,1/3) (-infty,infty) pi/18 left 0
8 2/3 2pi (-2/3,2/3) (-infty,infty) pi/3 left 0
