Chapter 14.3, Problem 19AYU

In Problems 7-42, find each limit algebraically.

$\underset{x\to 1}{\lim }\left(5x^4-3x^2+6x-9\right)$

To determine

To find: $\underset{x\to -6^{-}}{\lim }f\left(x\right)$

Answer to Problem 19AYU

$\infty$

Explanation of Solution

Calculation:

Since $f\left(x\right)$ approaches to infinity $\left(+\infty \right)$, as $x$ approaches to $-6$ from the left hand side; therefore $\underset{x\to -6^{-}}{\lim }f\left(x\right)=+\infty$.
