Question

Determine the demain and range for the relation in interval notation

Answer 1

`D=(-\infty,\infty),\:R=\lbrack-5\rbrack`

1) We can see that y=-5 is a constant function, graphically represented as a horizontal line passing through the point (0,-5).

2) Since this linear function has no restriction, no holes. We can tell its Domain is:

`D=(-\infty,\infty)`

3) When it comes to Range. We can tell that there is a single output is -5, so we can tell the Range of this function is:

`R=\lbrack-5\rbrack`
