Finding domain and range

Question

I am trying to find the domain and range of the function f(x)=2/3+x

Answer 1

Domain relates to values on the x-axis and range relates to those on the y-axis. When reading domain and range you are reading off of the graph on where the line goes through. With domain you read left to right and range you read from south to north.

With this equation, it is linear and includes all real numbers for both domain and range. So this would be (-∞,∞) for both the domain and range.

Answer 2

This is a linear equation, therefore the domain and range are both (-∞,∞) or all real numbers. There are no restrictions on either the domain or the range.
