In the function f(x) = (x^2 - 1)/(x^2 - 3x + 2), which of the following describes its hole and vertical asymptote?

In the function f(x) = (x^2 - 1)/(x^2 - 3x + 2), which of the following describes its hole and vertical asymptote?

• A. Hole at x = 1; Vertical asymptote at x = 2; simplified form f(x) = (x+1)/(x-2)
• B. Hole at x = 2; Vertical asymptote at x = 1; simplified form (x-1)/(x-2)
• C. Hole at x = -1; Vertical asymptote at x = -2; simplified form (x+1)/(x+2)
• D. No holes or asymptotes; function is continuous

Answer: (A)
