In mathematics, Limit of a function is used to show the value of a function to which it approaches and also behavior of function at a particular Point.
Mathematically, function with a limit is written as, Limp->a f (p) = f(q)
Here p--> a shows that “p” approaches to ‘a’.
Let the function be, y = f(x) = -2x2 + 8x – 4 and take the particular value of x = 3.
Limits calculator is a type of calculator that is used to calculate the value of function when its limit is provided. It has text space to take input for function and value of limit from user side and a “submit” button which on clicking shows the answer.
Steps to use Limits calculator:
Step 1: Enter the function in first text box. Step 2: Enter the value of limit in second text box Step 3: Click on ‘Submit’ button and we will get the answer.
Let’s take an example to use Limits calculator:
Step 1: Enter the function [2x + 3] in first text box. Step 2: Enter the value of the limit  in second text box Step 3: Click ‘Submit’ button and we will get answer .
