Limit Formula

In mathematics, limit is a fundamental concept in calculus and the behaviour concerns the function near that particular input. The formal definitions are first devised in the $19^{th}$ century, informally, when we say function f is assigned an output f(x) to every input x.

The limit of the function is calculated using limit formula.  

\[\large \lim_{x\rightarrow a}f\left(x\right)=A\]

Solved Examples

Question 1: Calculate $\lim_{x \rightarrow 2}$ 3x2 + 4x + 6 ?


$\lim_{x \rightarrow 2}$ 3x2 + 4x + 6

= 3(2)2 + 4(2) + 6
= 12 + 8 + 6
= 26
