Question

How do you find the domain and range and determine whether the relation is a function given :`y=7x-6`?

Answer 1

The relation is a function.
The domain and range are both all real numbers, or `(-oo, oo)`

Explanation:

First, this relation is a function. A function means that the input only has ONE output, or that each x-value can only have ONE y-value.

This equation `y = 7x - 6` is a line on the graph. All non-vertical lines are functions.

Also, since it is a line, that means that the domain and range are both all real numbers, or `(-oo, oo)`
