Solution

To determine the vertical asymptotes of the function f(x)=3x5x2f(x) = \frac{3x - 5}{x - 2}, we need to examine the points at which the function becomes undefined. Vertical asymptotes occur where the denominator of the function is zero, as long as the numerator does not also become zero at that same point (this would instead indicate a hole in the graph).

  1. Identify when the denominator is zero: Set the denominator equal to zero: x2=0x - 2 = 0 Solving this gives: x=2x = 2

  2. Check the numerator at x=2x = 2: Substitute x=2x = 2 into the numerator: 3(2)5=65=103(2) - 5 = 6 - 5 = 1 \neq 0 Since the numerator does not equal zero when x=2x = 2, there is indeed a vertical asymptote at x=2x = 2.

Since this is the only value of xx that makes the denominator zero, we conclude that the function has exactly one vertical asymptote at x=2x = 2.

Answer

The correct choice is: B. The function has one vertical asymptote, x=2x = 2.

Tip: For rational functions, always check if the numerator and denominator share common factors before concluding the presence of vertical asymptotes or holes.
