If one x-value does not have two y-values, then it is a function. In other words, x cannot be repeated. For example, take a parabola whose vertex is at the origin and points are all found in the first and fourth quadrants, forming a "c" of sorts. This graph would not pass the vertical-line test and would therefore not be considered a function.
A set of numbers is NEVER a function. A function is a special case of a RELATION between two sets of numbers (or some other sets). So, in the case of finite sets, you can express the function as a set of PAIRS OF NUMBERS, for example, {(0, 1), (1, 5), (2, 2), (3, 5), ...} Note that these are NOT numbers, rather, they are PAIRS of numbers.

Over the set of real numbers what is the domain of the composite function GF x?
The domain of your function is the set of real numbers.
What does discrete function mean?
Discrete Function - A function that is defined only for a set of numbers that can be listed, such as the set of whole numbers or the set of integers. Explicit Definition - A definition of a function by a formula in terms of the variable.
What is a set of numbers containing all of the inputs of a function called?
the domain of the function
What is Domain of the Function?
The domain of a function is the set of numbers that can be valid inputs into the function. Expressed another way, it is the set of numbers along the x-axis that have a corresponding solution on the y axis.
What is a set of numbers that can be substituted for a variable?
The domain of a function.
The average function is determined by dividing sum function by what function?
The average of a set of numbers is equal to the sum of those numbers divided by the number of numbers. So, one might say that the average function is equal to the sum function divided by the count function.
Is the average function is a mathematical function?
It is a statistical function specifically, finding a number that is a good representation of a set of numbers.
What is the function of large set of numbers?
There is no single function. In fact there are infinitely many possible functions.
How do you tell if a set of numbers is a function or not?
A set of numbers is never a function. A function is something that takes in a number and changes it into another number. For example y+2 takes in a number (y) and adds 2 to it. If y is 4, it produces 6.
How do you know about set in math?
by numbers
A sequence is a whose domain is the set of natural number?
A sequence is a function ! whose domian is the set of natural numbers
What is a picture created from a set of numbers?
It is a graph.
