Evaluating the limits from a graph.
When evaluating the limit of a function from its graph, distinguish between the function evaluated at the point and the limit around the point. The limit only exists when the left and right sides of the functions meet at a specific height, regardless of what the function is doing at that point.
What is the formula for evaluating a limit?
Limits formula:- Let y = f(x) as a function of x. If at a point x = a, f(x) takes indeterminate form, then we can consider the values of the function which is very near to a. If these values tend to some definite unique number as x tends to a, then that obtained unique number is called the limit of f(x) at x = a
