periodicity of y= 6/5 cos((2x)/7)

periodicity

y = \frac{6}{5} cos (\frac{2 x}{7})

7 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{2}{7}}

Simplify

= 7 π

f (x) = 4 x^{3} - 3 x^{2} - 36 x + 17

(x - 10)^{3} + 5

x^{2} + 2

\frac{1}{x - 2}
