Find (lim limits_{x to 3} frac{x + 3}{x^{2} – x – 12})
-
A.
-1 -
B.
(frac{-1}{7}) -
C.
(frac{1}{7}) -
D.
1
Correct Answer: Option A
Explanation
(lim limits_{x to 3} frac{x + 3}{x^{2} – x – 12} = frac{3 + 3}{3^{2} – 3 – 12})
= (frac{6}{-6} = -1)
Find (lim limits_{x to 3} frac{x + 3}{x^{2} – x – 12})
(lim limits_{x to 3} frac{x + 3}{x^{2} – x – 12} = frac{3 + 3}{3^{2} – 3 – 12})
= (frac{6}{-6} = -1)
