periodicity of-(cos((11pix)/6))/(2)-2

periodicity

- \frac{cos ( \frac{11 π x}{6} )}{2} - 2

\frac{12}{11}

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{11 π}{6}}

Simplify

= \frac{12}{11}

f (x) = \frac{x - 6}{x ^{2} - 36}

f (x) = 5 x + 13

\frac{2 x ^{2} + 2 x - 4}{x ^{2} + x}

f (x) = \frac{x + 6}{6 + x}

y = x + 4
