Question

If f x = max ⁡ x n , sin ⁡ π x , n ∈ N has maximum points of non-differentiability for x ∈ ( 0 , 4 ) , then n cannot be, 4, 2, 5, 6

MARKS App · Accepted Answer

f x = max ⁡ x n , sin ⁡ π x Thus, for the maximum points of non-differentiability, graphs of y = x n and y = sin ⁡ π x must intersect at maximum number of points which occurs when n > 3.5
