periodicity of f(x)=-2cos(2x)

Solution

periodicity

f (x) = - 2 cos (2 x)

Solution

π

Solution steps

Periodicity of

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

Periodicity of

cos (x)

is

2 π

= \frac{2 π}{∣ 2 ∣}

Simplify

= π

asymptotes of f(x)=(9x)/(x^2-2x-8)asymptotes

f (x) = \frac{9 x}{x ^{2} - 2 x - 8}

inverse of f(x)=e^{9x-8}inverse

f (x) = e^{9 x - 8}
