The curve has asymptotes and , and passes through the point . Find the value of .

Answer and explanation

Correct answer: C.

  1. Step 1: The vertical asymptote implies at , so . The horizontal asymptote as gives the coefficient ratio .
  2. Step 2: Substitute the known curve point : . Dividing by yields .
Answer
.
Why not the others: The value forgets the negative sign when rearranging ; the value confuses the ratio with the horizontal asymptote value; the value confuses the ratio with the vertical asymptote location.
