What is the domain of this function
y= |x|

Domain = all real numbers

Step-by-step explanation:

If you were to visualize what is, it would be a giant V shape, it's middle point being at (0,0). Since this is counted as a function and there is no end to the V shape, the domain would be all real numbers.

But there is a chance that there is a type of notation that your teacher will most likely ask you for (sometimes not), like set notation, etc. But if not provided, you can simply go with R (R stands for all real numbers) or {-∞<x<∞}.
