Question

The graph of the function f(x) = 4 is shown.


What is the domain of the function?

Answer 1

Hello, the answer would be all real numbers.

f(x) = 4 does not have any x variable, so it will be a solid horizontal line passing only y=4 and is parallel to the x-axis.

domain: -∞
`\leq`x
`\leq`∞ or R

Hope this helps!
