x+2=(y+1)^2

Let x = 0,then solve for "Y":
(y+1)^2 = 2
y+1 = +sqrt(2) or y+1 = -sqrt(2)
---
y = -1+sqrt(2) or y = -1-sqrt(2)
----
Those are the y-intercepts of the parabola.

Hi,         

  OR y = ± sqrt(x+2) - 1

 

 y-intercepts are when x= 0

 

 

  

  

  

   

   

   

      y = -2.414

      y = .414
