If every input has an output. If two outputs are the same, they must have the same input.
if there is an = sign
To determine if a relation given in a table is a function, check if each input (or x-value) corresponds to exactly one output (or y-value). This means that no x-value should appear more than once in the table with different y-values. If any x-value is paired with multiple y-values, the relation is not a function.
The domain of a function represented by a table consists of all the input values (usually the x-values) listed in the table. These values indicate the specific points at which the function is defined. To determine the domain, simply identify and list the unique x-values from the table. If any values are missing or not represented, they are excluded from the domain.
Sure you can. You might conclude that the table is clean, or dirty, or made of plastic or wood, or both. You might determine that the table is broken, and know whether it can be fixed or whether it needs to be replaced. Lots of conclusions can be drawn from a table. A table of data might lead you to draw other conclusions, accurately or inaccurately.
a function table is a table used to find number pairs
A virtual function table is a table of pointers to functions.
In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.

The MATCH function can find the position of an item in a table.
You can test the unknown crystalline substance by performing a taste test (table salt is salty), checking its solubility in water (table salt dissolves easily), and conducting a flame test (table salt will produce a yellow flame).
