periodicity of f(x)=-4cos(2x)

Solution

periodicity

f (x) = - 4 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

Popular Examples

periodicity of f(x)= 1/5 cos(3x-pi)periodicity

f (x) = \frac{1}{5} cos (3 x - π)

domain of f(x)=(9x-3)/(x-1)domain

f (x) = \frac{9 x - 3}{x - 1}

intercepts of f(x)=2x^2+3 intercepts

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

parity f(x)=x^3+4 parity

f (x) = x^{3} + 4

critical f(x)=(x^2)/(x-3)critical points

f (x) = \frac{x ^{2}}{x - 3}
