Question

What is indicated by the correspondence below?

Domain Correspondence Range

{-3, -1, 0, 1, 3} Each number's square {0, 1, 9}

Answer 1

The correspondence indicates a mathematical function that maps each number in the domain {-3, -1, 0, 1, 3} to its square in the range {0, 1, 9}.

For example, the number -3 in the domain corresponds to its square, which is 9, in the range. Similarly, the number 1 in the domain corresponds to its square, which is 1, in the range.

In general, for any number x in the domain, the corresponding value in the range is x^2. This correspondence defines a mathematical function that maps each number in the domain to its square in the range.
