Question

What is the domain and range described it interval notation. PLEASE HELPPP

Answer 1

For the given point
`\((-2, 4)\)`, the domain is
`\((- \infty, \infty)\)` and the range is
`\(\{4\}\)`

For the given point
`\((-2, 4)\)`, the domain and range can be described in interval notation.

1. Domain:

The domain of a function is the set of all possible input values (independent variable). In this case, the x-coordinate of the point
`\((-2, 4)\)` represents the input value. Therefore, the domain is simply the set of all possible x-values.

`\[ \text{Domain: } (-\infty, \infty) \]`

This interval notation
`\((-\infty, \infty)\)` indicates that the x-values can be any real number.

2. Range:

The range of a function is the set of all possible output values (dependent variable). In this case, the y-coordinate of the point
`\((-2, 4)\)`represents the output value. Therefore, the range is the set containing only that y-value.

`\[ \text{Range: } \{4\} \]`

This interval notation
`\(\{4\}\)` indicates that the y-values can only be 4.
