Question

Difference between domain co domain

Answer 1

The Codomain is the set of values that could possibly come out. TheCodomain is actually part of the definition of the function. And The Range is the set of values that actually do come out. Example: we can define a function f(x)=2x with a domain andcodomain of integers (because we say so).The domain of a function is the complete set of possible values of the independent variable. In plain English, this definition means: The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

Answer 2

Answer:

The Codomain is the set of values that could possibly come out. The domain of a function is the set of all possible inputs for the function.

Step-by-step explanation:

to exactly one element in the codomain. The Domain is the set of input numbers, For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.   the Codomain is the set of possible output numbers, The codomain of a function is the set of its possible outputs. In the function machine metaphor, the codomain is the set of objects that might possible come out of the machine. For example, when we use the function notation f:R→R, we mean that f is a function from the real numbers to the real numbers.
