periodicity of f(x)=-6cos(3x)+4

periodicity

f (x) = - 6 cos (3 x) + 4

\frac{2 π}{3}

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}{∣ 3 ∣}

Simplify

= \frac{2 π}{3}

f (x) = 6 x + 4

\frac{( x + 1 )}{x ^{2} - 4}

f (x) = \frac{5 - x}{3 + 2 x}

f (x) = 3 x^{2} + 5 x - 2

y = \frac{1}{4} x + 7

What is the periodicity of f(x)=-6cos(3x)+4 ?
The periodicity of f(x)=-6cos(3x)+4 is (2pi)/3
