Correct answer

0

Step-by-step solution


Let f: [0, 4π] → [0, π] be defined by f(x) = ^ - 1 (cos x) . The number of points x ∈ [0, 4π] satisfying the equation
f:[0,4π]→[0,π],f(x)=cos⁡−1(cosx)f: \left[0, 4\pi\right] \to \left[0, \pi\right], f\left(x\right) = \cos^{- 1} \left(cos x\right)
⇒⇒ Point A, B, C satisfy f(x)=10−x10f\left(x\right) = \dfrac{10 - x}{10}
Hence. 3 points
