Describe the method of evaluating limits graphically. Give at least one disadvantage of this method.

To determine

The method that is used to evaluate the limits graphically and also its disadvantage.

Explanation

Consider the expression, limxaf(x)

To evaluate the provided limit that is, limxaf(x) graphically, the following method is followed:

Consider the function f(x).

Draw the graph of f(x) either by hand or with graphing technology.

Then point the trace cursor or pencil point on a point of the graph to the left of x=a.

Move the point along the curve towards x=a from the left and notice the y-coordinate also. The value that the y-coordinate approaches towards is the limit limxaf(x)
