Domain And Range Interval Notation Khan Academy

In this video sal introduces the different types of interv.

Domain and range interval notation khan academy. Khan academy is a 501 c 3 nonprofit organization. So the domain of this function definition. Domain and range from graph our mission is to provide a free world class education to anyone anywhere.

Let s say i wanted to talk about the interval on the number line that goes from negative three to two. Well f of x is defined for any x that is greater than or equal to negative 6. We can also define special functions whose domains are more limited.

Voiceover what i hope to do in this video is get familiar with the notion of an interval and also think about ways that we can show an interval or interval notation. Functions assign outputs to inputs. запознаване с интервалите които представляват ограничени множества от стойности и са много използвани при описване на дефиниционното множество и множеството от стойности на една функция.

So that s its domain. увођење интервала што су ограничени скупови бројева јесте веома корисно при описивању домена и кодомена.

So let s check our answer. можем да използваме. Or we could say negative 6 is less than or equal to x which is less than or equal to 7.

Intervals describe specific sets of numbers and are very useful when discussing domain and range. The domain of a function is the set of all possible inputs for the function.
