Domain of a function video. Sal introduces the concept of domain of a function and gives various examples for functions and their domains watch the next lesson. Remember the domain of a function is the set of possible inputs to that function. First we remember that the domain is the set of all possible 𝑥 values for a function.
The function 𝑓 of 𝑥 here is represented by these five points. The domain of a function is the set of all possible inputs for the function. Such ideas are seen in high school and first ye.
For example the domain of f x x is all real numbers and the domain of g x 1 x is all real numbers except for x 0. It s the quotient of two polynomials. Find the domain of the real function 𝑓 of 𝑥 equals 𝑥 plus 48 over 𝑥 cubed minus 343.
We can also define special functions whose domains are more limited. Mit grad shows a surefire way to find the domain of any function. Functions assign outputs to inputs.
The domain of the function 𝑓 of 𝑥 is blank.
