WebSince f (x) is not defined at x=0, it could be argued that the domain is (-∞,0) U (0,∞) in which case 0 is not part of the domain and the function is continuous over its domain. However, if you consider the domain to be all real numbers, it is not continuous. Webf (x) = x2 shows us that function " f " takes " x " and squares it. Example: with f (x) = x2: an input of 4 becomes an output of 16. In fact we can write f (4) = 16. The "x" is Just a Place-Holder! Don't get too concerned about "x", it is just there to show us where the input goes and what happens to it. It could be anything! So this function: chip governoWebf(x) = 2 . f(1) = 2 . f(1) = 2 therefore the function is defined at x = 1 and passes . the first test of continuity. Test 2: () 1 lim x. f xexists →.

Webf (x) is defined and the limit at x equals f (x) Here are some examples: Example: f (x) = (x 2 −1)/ (x−1) for all Real Numbers The function is undefined when x=1: (x 2 −1)/ (x−1) = (1 2 −1)/ (1−1) = 0/0 So it is not a continuous function Let us change the domain: Example: g (x) = (x 2 −1)/ (x−1) over the interval x<1 chip gratis a domicilioWebf(x) therefore is continuous at x = 8. (Definition 3.)In this same way, we could show that the function is continuous at all values of x except x = 2..
