Math Problem Statement

As x approaches 2 from the right (x → 2^+), what happens to f(x)?

Solution

The image shows a rational function graph with vertical asymptotes at x=4x = -4 and x=2x = 2, and a horizontal asymptote at y=3y = -3. Based on this graph, we need to complete the statements related to the behavior of the function as xx approaches 2 from the right (x2+x \to 2^+).

  1. As x2+x \to 2^+, f(x)+f(x) \to +\infty: The graph indicates that the function tends to infinity as xx approaches 2 from the right, meaning it shoots upwards near the asymptote at x=2x = 2.

  2. As x2x \to 2^-, f(x)f(x) \to -\infty: From the left side, as xx approaches 2, the function decreases without bound, meaning it heads downwards toward negative infinity.

These behaviors describe how the function approaches its vertical asymptote at x=2x = 2. The dashed vertical line at x=2x = 2 indicates that the function cannot cross this point, but the values approach infinity from either side.

Tip: Vertical asymptotes occur where the denominator of a rational function equals zero, and the function's behavior around these points often involves values tending towards \infty or -\infty.
