What would be the domain of (1/x+2^2) + squareroot of 1-x? What would be the domain and range of square root of 9-xsquared?

I could tell you if I could step back in time about 12 years Amazing how fast advanced math leaves you if you don't work with it. Good luck.
Graph shows points at (-3, 0), (3,0), and (0,3) as a semi circle for the squareroot of 9-xsquared, so would the domain me [-3, 3] and the range (0,3)??
on the second problem, I think the domain is -3 < x < 3. I'm not sure how you write that with the parentheses and brackets. The range should be 0 < y < 3. on the first problem, is the x+2 squared or what?
ok so the denominator cannot be zero, so that means x cannot equal -2 for that part of the equation. now for the sqrt of 1-x, x < 1 since the sqrt cannot be negative. combine that and you get (-infinity, -2) u (-2,1). I think you can figure out the range from there...
Plates im confused if its a bracket or a paranthesis, I think with the bracket, it means it includes the outside number, and if it was paranthesis it would not include it.. For example (0, 5) would be like numbers 0-5 NOT including 0 and 5 [0, 5] would be numbers INCLUDING 0 and 5... So was the answer ou gave me for the domain right??
yes I gave you the domain. and yes, parentheses means it does not include and brackets mean the number is included. so it should be (-infinity, -2) u (-2,1]
I believe so. Don't hold me accountable lol. Checking it on a graph is the easiest way. and range should be [0,3]
First one's domain looks like all real numbers greater than 1 except for -4; or (0,1]. The range looks like 5 to infinity, but you have not written this problem very well. The domain on the second one could be [-3,3]. The range would then be [0,9].
