Question 704802:  what are the domain and range of the following equations? 
1. y=3x^2-6 
2. y=sqrt(x^2-4) 
3. y=|3x+2| 
4. y={ -2 if x<=3; 2 if x>3} 
5. y={ x^2-4 if x<3; 2x-1 if x>=3} 
6. y= [(x+1)(x^2+3x-10)]/ x^2+6x+5

You can  put this solution on YOUR website! (1)domain=========all real numbers,,,,,,,range====y≥-6,[-6,∞)
 
(2)domain==x≤-2,ORx≥2 
range======+y>0
 
(3)domain==a.r.n 
range=+y≥0
 
(4)domain====a.r.n 
range=+y>1,3
 
(5)domain=a.r.n 
range=x.3
 
(6)domain=x#0,(-∞,0)U(0,∞) 
range a.r.n
