We will now estimate the limit of the function f of x as x approaches 4.
00:06
The function f of x is given as x minus 4 over x squared minus 3x minus 4.
00:11
And so to evaluate this limit as x approaches 4, we take a few values which are closer to the 4, that is both from left side as well as from the right side.
00:23
So in this table we have a few values like 3 .99, 3 .999 and 4 .01.
00:32
These x values are closer to 4 .01.
00:36
And we have to find the corresponding function values for these values of x.
00:41
So first i have used the calculator to find the function values.
00:46
At the values of x 3 .99, 3 .99, as well as when x is 4 .001, and 4 .01.
00:56
Now to estimate this limit, we basically take the values of x, which are closer on both sides...
