Let (btext{,}) (ctext{,}) (L) and (K) be real numbers, let (n) be a positive integer, and let (f) and (g) be functions with the following limits: begin{align*}lim_{xto c}f(x)amp=Lamplim_{xto c} g(x)amp = Ktext{.}end{align*}

Given a function y = f. ( x) and an x -value, c, we say that “the limit of the function f, as x approaches c, is a value L ”: 1. If “ y tends to L ” as “ x tends to c.”. If “ y approaches L ” as “ x approaches c.”. If “ y is near L ” whenever “ x is near c.”. Limits describe how a function behaves near a point, instead of at that point. This simple yet powerful idea is the basis of all of calculus.

The following limits hold.


(limlimits_{xto c} b = b)


(limlimits_{xto c} x = c)


(limlimits_{xto c}(f(x)pm g(x)) = Lpm K)

Scalar Multiple

(limlimits_{xto c}(bcdot f(x)) = bL)

1.2 Limits Analyticallyap Calculus

(limlimits_{xto c} (f(x)cdot g(x)) = LK)


(limlimits_{xto c} (f(x)/g(x)) = L/Ktext{,}) when (Kneq 0)


(limlimits_{xto c} f(x)^n = L^n)


(limlimits_{xto c} sqrt[n]{f(x)} = sqrt[n]{L})

(If (n) is even, (L) must be non-negative.)


If either of the following holds:

  1. (limlimits_{xto c}f(x)=Ltext{,}) (limlimits_{xto L}g(x)=Ktext{,}) and (g(L)=K)

  2. (limlimits_{xto c}f(x)=Ltext{,}) (limlimits_{xto L}g(x)=Ktext{,}) and (f(x)neq L) for all (x) close to but not equal to (c)


then (limlimits_{xto c}g(f(x)) = Ktext{.})


$limlimits f(x)_{x to c}$ exists for all values of c except for at $c=4$

A limit is the $y$ value of a function as it gets infinitely close to an $x$ value. A limit exists if $lim limits f(x)_{xto c^{-}}$ $=$ $lim limits f(x)_{xto c^{+}}$. When finding limits on a piecewise function, you first check to make sure each individual 'piece' exists at the given bounds. Then you make sure that at the endpoints of each boundary, the two functions equal each other. In this problem, $limlimits f(x)_{a to 2^{-}}=4$ and $limlimits f(x)_{a to 2^{+}}=4$. However, at the other boundary $x=4$, $lim limits f(x)_{xto 4^{-}}= 0$ and $lim limits f(x)_{xto 4^{+}}=4$, so the limit does not exist at $x=4$
