Answer:
[tex]Domain: \left \{ -\infty<x<\infty \\\right\}[/tex]
[tex]Range:\left\{-\infty<f(x)<\infty\right\}[/tex]
Step-by-step explanation:
[tex]x+y=180[/tex]
First, let's put this equation into slope-intercept form by subtracting [tex]x[/tex] from both sides of the equation:
[tex]y=-x+180[/tex]
Let's graph this (see the attached photo.)
As you see we have a straight line. If you are able to graph a straight line, the domain and range will be all real numbers. This can be represented as:
[tex]Domain: \left \{ -\infty<x<\infty \\\right\}[/tex]
- or -
[tex]Domain:(-\infty,\infty)[/tex]
~
[tex]Range:\left\{-\infty<f(x)<\infty\right\}[/tex]
- or -
[tex]Range:(-\infty,\infty)[/tex]
