**Finding limits with direct substitution StudyPug**

How to find the following limit algebraically? Ask Question 7. 1. I've been trying to answer this for a while and I know it's a simple question relative to most questions that are posted here. $$ \lim_{x\rightarrow -2}\: \frac{x^4+5x^3+6x^2}{x^2(x+1)-4(x+1)} $$ If we substitute -2 for $ x $ we get $ 0/0 $, an indeterminate form. I figured that the denominator can be rewritten as $ (x^2-4)(x+1... The above limit laws allow us to use algebra to break limits apart. But sometimes we use algebra inside the limit. For example, in evaluating the "speed limit" (10 + h) 2 - 100: lim: h --> 0: h: we used algebra to expand the numerator and then cancel an h from the numerator an denominator. This had the effect of replacing the original function, which was not defined at h=0, by an algebraically

When substitution doesn’t work in the original limit function — usually because of a hole in the function — you can often use some algebra to manipulate the function until substitution does work (it works because your manipulation plugs up the hole).... 9/07/2015 · Upload failed.

- Functions and Domains . A real-valued function f of a real variableis a rule that assigns to each real number x in a specified set of numbers, called the domain of f, a single real number f(x).
- Calculus Limits Determining Limits Algebraically. Key Questions . How do you find one sided limits algebraically? When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples. #lim_{x to 0^-}1/x=1/{0^-}=-infty# 1 is divided by a number approaching 0, so
