shift f(x)=9cos(1/3 pix+pi)-2

shift

f (x) = 9 cos (\frac{1}{3} π x + π) - 2

Phase : - 3, Vertical : - 2

Solution steps

Simplify

9 cos (\frac{1}{3} π x + π) - 2 : 9 cos (\frac{π}{3} x + π) - 2

f (x) = 9 cos (\frac{π}{3} x + π) - 2

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

Therefore, the phase shift

\frac{C}{B}

\frac{- π}{\frac{π}{3}}

- 3

The vertical shift

D

- 2

- 2
