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.
Q. What is principle identity?
1. in logic, the principle that where X is known to be identical to Y, any statement about X (or Y) will have the same meaning and truth value as the same statement about Y (or X).

Q. What is identity rule?
In logic, the law of identity states that each thing is identical with itself. In its formal representation, the law of identity is written “a = a” or “For all x: x = x”, where a or x refer to a term rather than a proposition, and thus the law of identity is not used in propositional logic.
Q. How do you prove a function is identity?
To “prove” an identity, you have to use logical steps to show that one side of the equation can be transformed into the other side of the equation. You do not plug values into the identity to “prove” anything. There are infinitely-many values you can plug in.
Q. What is the constant rule?
The rule for differentiating constant functions is called the constant rule. It states that the derivative of a constant function is zero; that is, since a constant function is a horizontal line, the slope, or the rate of change, of a constant function is 0. If f(x)=c, then f′(c)=0.
Q. What is the derivative of zero?
The derivative of 0 is 0. In general, we have the following rule for finding the derivative of a constant function, f(x) = a.
Q. What is constant number?
more A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in “x + 5 = 9”, 5 and 9 are constants.
Q. Can zero divide a number?
0 Divided by a Number 0a=0 Dividing 0 by any number gives us a zero. Zero will never change when multiplying or dividing any number by it. Finally, probably the most important rule is: a0 is undefined You cannot divide a number by zero!
Q. What makes mathematicians great?
Someone who can formulate ideas and do so through proofs and axioms. Someone who can creatively produce ideas while being insightful of current mathematical knowledge. Constantly tinkering and expanding the knowledge of mathematics makes a person a good mathematician.
