shift f(x)=9cos(1/4 pix-pi)-2

shift

f (x) = 9 cos (\frac{1}{4} π x - π) - 2

Phase : 4, Vertical : - 2

Solution steps

Simplify

9 cos (\frac{1}{4} π x - π) - 2 : 9 cos (\frac{π}{4} x - π) - 2

f (x) = 9 cos (\frac{π}{4} x - π) - 2

g (B x - C) = cos (\frac{π}{4} x - π), B = \frac{π}{4}, C = π, D = - 2

Therefore, the phase shift

\frac{C}{B}

\frac{π}{\frac{π}{4}}

4

The vertical shift

D

- 2

- 2

8 x + 10 y = - 60

f (x) = 6 x - 8

f (x) = 5 x - 6

sin (3 x)

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