Identify the domain and range of the following: f(x) = 4-x^2, -5<x<-1 3/2x + 3/2, -1<x<3 (both "<" signs are actually less than or equal to) x+3, 3<x<10 (x<10 is actually less than or equal to) All three are in a set. I'd like to say that the domain is ...

how do i find the domain and range of equations? example: f(x)=ab.solute value of x-3. f(x)=square root 36-x^2 g(x)=-2x+2. do i find the range by pluggin in y for the x and then solving. for example: x=-2y+2, and then i get y=x-2/-2. and then is that how i find the range...

**math**

how come in y=x^2, the range is all real numbers, y is greater than or equal to 0 or is it for x=y^2? in y=x^2 imagine any choice of x (the domain) you might make. No matter what x you choose, once you square it, it becomes positve. So y can never be a negative number, ...

**Discrete Math**

Determine the domain and range of: y = 5 [1/ (1 + x)] So, would the domain be all real numbers except -1? And would the range be all real numbers except zero? I'm really confused. . .
