shift f(x)=-3cos(-2x+pi/2)

shift

f (x) = - 3 cos (- 2 x + \frac{π}{2})

Phase : \frac{π}{4}, Vertical : 0

Solution steps

f (x) = - 3 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

- - x^{2} - 4 x + 5 + 3

f (x) = \frac{2}{3} x - 1

e^{x^{2} - 6 x + 8}

(- 8, - 10), (0, - 3)

m = - \frac{5}{2}, (1, 3)
