Consider the function $f(x)={x}^{2/3}{(6-x)}^{1/3}$. Which of the following statement is false?

Solution

Given Function: $$f(x) = x^{2/3}(6 - x)^{1/3}$$

  • f is increasing in (0, 4): ✅ True
  • f has a point of inflection at x = 0: ✅ True
  • f has a point of inflection at x = 6: ✅ True
  • f is decreasing in (6, ∞): ❌ False (function not defined there)

Correct Answer (False Statement): $$\boxed{\text{f is decreasing in } (6, \infty)}$$
