Question

Let $f(x) = 5 - |x-2|$ and $g(x) = |x + 1|$, $x \in \mathbb{R}$. If $f(x)$ attains maximum value at $\alpha$ and $g(x)$ attains minimum value at $\beta$, then $\lim_{x \to \alpha\beta} \frac{(x-1)(x^2-5x+6)}{x^2-6x+8}$ is equal to}

• A. $\frac{1}{2}$
• B. $-\frac{3}{2}$
• C. $-\frac{1}{2}$
• D. $\frac{3}{2}$

Hint:

When encountering discrepancies between a problem statement and a provided answer in multiple-choice questions, analyze the solution steps carefully. Sometimes, the intended limit point or variable might be different from what's explicitly written. For rational functions, factorize polynomials to identify and cancel common factors before substituting the limit value.

Answer 1

The Correct Option is A
