Answer:
Step-by-step explanation:
3)
Amplitude = coefficient of cos = 1/2
Phase shift = horizontal shift = -pi/2(left)
Vertical shift = 1 (1 unit up)
Period = 2pi/coefficient of x = pi/2
Vertical dilation by scale factor 2
------------------------
4) Amplitude = coefficient of cos = 2
Phase shift = horizontal shift = -pi/2(right)
Vertical shift = 2 (2 unit up)
Period = 2pi/coefficient of x = pi
Vertical shrink by scle factor 2
---------------------------------
5) Amplitude = coefficient of sin = 3/4
Phase shift = horizontal shift =0
Vertical shift = 0
Period = 2pi/coefficient of x =3 pi/4
Vertical dilation by scale factor of 4/3
