shift y=6cos(2x+pi/2)

shift

y = 6 cos (2 x + \frac{π}{2})

Phase : - \frac{π}{4}, Vertical : 0

Solution steps

f (x) = 6 cos (2 x + \frac{π}{2})

g (B x - C) = cos (2 x + \frac{π}{2}), B = 2, C = - \frac{π}{2}, D = 0

Therefore, the phase shift

\frac{C}{B}

\frac{- \frac{π}{2}}{2}

- \frac{π}{4}

The vertical shift

D

0

0

f (x) = - 3 x^{2} - 6 x + 8

f (x) = \frac{x - 4}{x - 8}

y = 2 x - x^{2}

- 25 - x^{2}

\frac{x - 1}{x + 1}
