Asked by Jay
How would you write the domain (x is greater than or equal to -9) and range (x is greater than or equal to -4) in interval notation? I have D= {x∈R: x ≥ -9} for the domain but does that cover the range? Or do I have to write out the range like that?

Take a peek at this video, it explains the interval notation

So after watching it, let me know what you decide.
Btw, to indicate the range, we usually refer to the y , not the x
so your range stated the normal way would be:
range = {y∈R: y ≥ -4}
