Exercise
$\lim_{x\to-\infty}\frac{-5}{2x^3}-7+\frac{8}{x}$
Step-by-step Solution
Learn how to solve operations with infinity problems step by step online. Find the limit of -5/(2x^3)-78/x as x approaches -infinity. Evaluate the limit \lim_{x\to{- \infty }}\left(\frac{-5}{2x^3}-7+\frac{8}{x}\right) by replacing all occurrences of x by - \infty . Any expression divided by infinity is equal to zero. Simplify \left(- \infty \right)^3 by taking the minus sign (-) out of the power. Infinity to the power of any positive number is equal to infinity, so \infty ^3=\infty.
