Question

Identify the domain and range for the table from problem #5 of your assignment. Also, determine if it represents a function.

Answer 1

Domain: {4,5,7,10}

Range: {2,4,8}

Not a function

Explanation:

The domain is all the x-values.

The range is all the y-values.

However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.
