Question 212721: which ordered pair is the vertex of y=[x+2]-1?
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! which ordered pair is the vertex of y=[x+2]-1?
--------------------------------------------------
I assume the x+2 is surrounded by absolute value notation.
-----
If that is true |x+2| has its lowest value at x = -2
The y-value when x = -2 is -1.
So the vertex must be at (-2,-1)
