Math Problem Statement

Find holes of f(x)=(x+3)/(x+2)

Solution

To find the holes of the function f(x)=x+3x+2f(x) = \frac{x+3}{x+2}, we analyze its numerator and denominator to identify any removable discontinuities. Here’s the step-by-step process:

Steps:

  1. Factorize the numerator and denominator:

    • f(x)=x+3x+2f(x) = \frac{x+3}{x+2}.

    The numerator and denominator are already fully simplified.

  2. Identify potential holes:

    • A hole occurs where the denominator is zero, but the corresponding factor also cancels in the numerator.
    • The denominator x+2x+2 equals zero when x=2x = -2.
  3. Check for cancellation:

    • There is no x+2x+2 term in the numerator to cancel with x+2x+2 in the denominator. Thus, there is no hole.

Conclusion:

The function f(x)f(x) has no holes. It has a vertical asymptote at x=2x = -2, since the denominator becomes zero there, but the numerator does not.

Would you like more details on vertical asymptotes or further clarification?

Tip:

Always simplify the rational function first before analyzing for holes or asymptotes.
