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

shift

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

Phase : 0, Vertical : - 2

Solution steps

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

g (B x - C) = cos (\frac{2}{3} x), B = \frac{2}{3}, C = 0, D = - 2

Therefore, the phase shift

\frac{C}{B}

\frac{0}{\frac{2}{3}}

0

The vertical shift

D

- 2

- 2

f (x) = x^{3} - 4 x^{2} + x + 6

2 cos (4 x + \frac{π}{2})

\frac{3}{x ^{2} + 2 x}

f (x) = x^{3} - 3 x^{2} + 12

\frac{s - 1}{s - 4}
