shift-2cos(x/3-pi/9)-3

shift

- 2 cos (\frac{x}{3} - \frac{π}{9}) - 3

Phase : \frac{π}{3}, Vertical : - 3

Solution steps

f (x) = - 2 cos (\frac{x}{3} - \frac{π}{9}) - 3

g (B x - C) = cos (\frac{x}{3} - \frac{π}{9}), B = \frac{1}{3}, C = \frac{π}{9}, D = - 3

Therefore, the phase shift

\frac{C}{B}

\frac{\frac{π}{9}}{\frac{1}{3}}

\frac{π}{3}

The vertical shift

D

- 3

- 3

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

f (x) = 4 - \frac{2}{t ^{2}}

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

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

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