  1. For each trigonometric function:
    (i) Graph the trigonometric function for one period.
    (ii) State the vertical displacement, phase shift, period, and amplitude.
    (iii) State the domain and the range.
    1. y=2sinπ4(x+3)+1y = 2\sin \frac{\pi }{4}(x + 3) + 1
    2. y=3sec(π2xπ)1y = 3\sec (\frac{\pi }{2}x - \pi ) - 1
    3. y=2sin(4x+4π)3y = - 2\sin (4x + 4\pi ) - 3
  2. For the trigonometric function: y=tan(  x3π6  )y = - \tan \left( {\;\frac{x}{3} - \frac{\pi }{6}\;} \right)
    i) Graph the trigonometric function for two periods.
    ii) State the domain and the range.
