Math Problem Statement

f(x)=(\root(3)(x))/(x-3)

Solution

The function you're dealing with is:

f(x)=x3x3f(x) = \frac{\sqrt[3]{x}}{x - 3}

This function consists of two components:

  1. The cube root of xx, written as x3\sqrt[3]{x} or x1/3x^{1/3}.
  2. The denominator x3x - 3, which introduces a potential issue if x=3x = 3 because it would make the denominator zero.

Important points:

  • Domain: The domain is all real numbers except x=3x = 3, where the denominator is zero and the function is undefined.
  • Continuity: The function is continuous everywhere except at x=3x = 3.
  • Asymptote: Since the denominator goes to zero as xx approaches 3, there is a vertical asymptote at x=3x = 3.

Would you like further details on graphing this function, analyzing its asymptotes, or differentiating it?

Follow-up questions:

  1. What is the domain and range of f(x)f(x)?
  2. How do you find the vertical asymptote of f(x)f(x)?
  3. Can you find the critical points of f(x)f(x) using derivatives?
  4. How does the function behave near the vertical asymptote at x=3x = 3?
  5. Can you determine any local extrema for f(x)f(x)?

Tip:

When working with rational functions, always check for points where the denominator might become zero, as these are where vertical asymptotes may occur.
