In everyday life, we come across different types of limits. For example, while you drive a car you'll have limit to its speed, when you try to lift a box, you'll have a limit to your weight you lift and when you try to stretch a spring, you'll only have a limited expansion depending on your body strength. 

All these phrases suggest that limit is a bound, in which some occasion it may be reached or exceeded but on other occasions may not be reached. Limit calculator is a great mathematical tool for understanding  limits. It can often give you a better feel for how a limit works.
In maths, limit is expressed assuming that f(x) is a real-valued function and z is a real number. The expression
   $ \lim_{x \to z}f(x) = N$

means that f(x) can be created to be as near to "N" as preferred by creating x adequately near to z.
The given limit calculator work according to the rule that the calculator will takes the  given function and calculates the limit of the function for the given variable value that needs to be measured.

Steps involved for using calculator: 
1. Enter the function for which one has to find the limit.  
2. Enter the variable value which needs to be measured.
3. Hit 'Submit' for calculating the limit of the function.

When the solution is a real number, then the number is consider as the given functions limit. When the solution is infinity, limit of the function doesn't exists.

Solved Examples

Question 1: Solve $\lim_{x \to2}(2x + 20)$
$\lim_{x \to 2}(2x + 20)$

 = $\lim_{x \to 2}(2x + 20)$

= $2 \times 2  + 20$

 = $4 + 20$

= $24$

Answer: $24$

Question 2: Solve $\lim_{x \to2}(5x2 - 8y + 6)$
$\lim_{x \to 2} (5x^{2} - 8y + 6)$
   = $\lim_{x \to 2} (5x^{2} - 8y + 6)$

 = $5(2)^{2} - 8(y) + 6$

 = $20 - 8y + 6$

 = $26 - 8y$

Answer:  $26 - 8y$
