periodicity of f(x)=-1/3 cos(1/3 x)

periodicity

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

6 π

Solution steps

Periodicity of

a \cdot cos (b x + c) + d = \frac{periodicity of cos ( x )}{∣ b ∣}

Periodicity of

cos (x)

2 π

= \frac{2 π}{\frac{1}{3}}

Simplify

= 6 π

(x - 9)^{2}

x^{3} - 3 x + 3

y = \frac{1}{4 - 2}

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

\frac{3 + \frac{6}{s - 3}}{s - 2 + \frac{4}{s - 3}}
