Math Problem Statement

Write an equation for the function graphed below

Solution

To determine the equation for the function graphed in the image, let's analyze the key features visible:

  1. Vertical Asymptotes: The graph has vertical asymptotes at x=3x = -3 and x=2x = 2. This suggests that the function likely has factors in the denominator that cause the function to approach infinity as xx approaches these values.

  2. Behavior of the Function: The graph resembles a rational function with vertical asymptotes and undefined points. Given the asymptotes at x=3x = -3 and x=2x = 2, the denominator of the function could include factors like (x+3)(x2)(x + 3)(x - 2).

  3. Horizontal Asymptote: The function seems to level off towards a horizontal asymptote at y=0y = 0 as xx moves to positive and negative infinity, indicating that the degree of the numerator is lower than or equal to the degree of the denominator.

A basic function that meets these conditions would be: y=1(x+3)(x2)y = \frac{1}{(x + 3)(x - 2)}

This form has vertical asymptotes at x=3x = -3 and x=2x = 2, as well as a horizontal asymptote at y=0y = 0.

Final Answer:

y=1(x+3)(x2)y = \frac{1}{(x + 3)(x - 2)}

Would you like a deeper explanation of this solution or have any other questions?

Here are some related questions to expand your understanding:

  1. What would happen if the numerator had a term x2x^2 instead of a constant?
  2. How do vertical asymptotes affect the shape of a graph?
  3. What conditions lead to a horizontal asymptote at y=0y = 0?
  4. Can a rational function have more than two vertical asymptotes?
  5. How would the equation change if there were a horizontal asymptote at y=2y = 2?

Tip: For rational functions, vertical asymptotes occur where the denominator equals zero (and the numerator doesn’t also go to zero at those points).
