Hi, Can you please help me?
I need help finding the domain, and range of this piecewise defined function

I think the domain is ( +-+infinity+, +%2B+infinity+ )
.
I think the range is ( +-+infinity+, 6 ] U (12,30) U [100, +%2B+infinity+ )
.
Are these right? Can you please confirm, please use interval notation, just like what I did for domain, and range
.
Thanks ahead of time,Levi 

Here's the graph:



Yes you're right for domain and range!
