What is the equation of the vertical asymptote of f(x) = (3x + 2) / (x - 1)?
Answer and explanation
Correct answer: D. x = 1
- Step 1: The denominator vanishes at x = 1 while the numerator equals 5, which is not zero.
- Step 2: So the vertical asymptote is x = 1.
Answer
x = 1.
Why not the others: y = 3 is the horizontal asymptote; x = -1 has the wrong sign; y = 1 is not an asymptote.
