Question

find the domain and range on the function f(x)=x^2+2x+1,x belongs to N(N=set of natural numbers)

Answer 1

Answer:

The domain of a function f (x) is the set of all values ​​for which the function is defined, and the range of the function is the set of all values ​​that f takes. (In grammar, you probably call the domain the replacement set and the range the solution set.

Step-by-step explanation:

Domain and range of the function f (x) = 1 / x

Domain are all the values ​​that x can have, if the value of x is 0, you would have 1/0, which is an indeterminacy and therefore 0 is not a real value for the domain.

The range of g is the interval [1, 10] (see the diagram in the previous figure). Problem. 17. Find the domain and range of the function f (x) = x2 + 4.

The most effective way to determine the Range is to graph the function and see the values ​​that “Y” takes from bottom to top. In other words, they are the values ​​that the variable “y” has for certain values ​​of x, in that function (the values ​​that actually come out).
