If the line x + y = 1 touches the parabola y2 – y + x = 0 and h = value of x where | x | is not differentiable, k = lim⁡n→∞\lim_{n \rightarrow \infty}cos2nx, where x = np, n ÎI. then the point of contact is

A

(h, h)

B

(h, k)

C

(k, h)

D

(k, k)

Answer

(h, k)

Explanation

Solution

h = 0 where |x| is non differentiable

k = 1. POC: (h, k)
