Question

X + y = 180. what is domain and range

Answer 1

`Domain: \left \{ -\infty<x<\infty \\\right\}`

`Range:\left\{-\infty<f(x)<\infty\right\}`

Explanation:

`x+y=180`

First, let's put this equation into slope-intercept form by subtracting
`x` from both sides of the equation:

`y=-x+180`

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:

`Domain: \left \{ -\infty<x<\infty \\\right\}`

- or -

`Domain:(-\infty,\infty)`

~

`Range:\left\{-\infty<f(x)<\infty\right\}`

- or -

`Range:(-\infty,\infty)`
