Answer: function
Step-by-step explanation:
Functions are relationships or rules that assign each value of the independent variable (Domain) exactly one value of the dependent variable (Range)
For example if we have the following function:
[tex]f (x) = 2x[/tex]
The independent variable is x.
Notice that when:
[tex]x = 1, f (x) = 2\\x = 2, f (x) = 4\\x = 3, f (x) = 6[/tex]
In this way the function assigns an output value to each input value.
Therefore the answer is:
A_function_ is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.
