Question

Functions can be defined using graphs, tables, and ordered pairs. What is the range of a function? Group of answer choices

The range is any x-value.
The range is the output.
The range is the input.
The range is all numbers.

Answer 1

The range is the output of any given function for all possible values of x.

Explanation:

Range of a function : It is the set of all possible resulting values when we have substituted every possible value x for the given function.

if y = f(x) is the given function, then

y : { Set of all resulting answered} = Range

and x : { set of all values substituted} = Domain

Hence, the range is the output of any given function for all possible values.

Answer 2

The range is the output.

Explanation:

A function consists of two parts:

1. Domain - Domain is the set of all values that are inputted to a function. So, domain is set of all possible values of
`x`.

2. Range - It is the set of all output values for given input values. It is the set of all possible values of
`y` for given
`x` values.

Therefore, range is the output to a function.
