i need to know what y equals
the vertex
a of S: x=
min/max
x-int
y-int
inc: x __ __
dec: x __ __
x -> *infinity sign* ; y->
x -> - *infinity sign* ; y->

You can put this solution on YOUR website!
y=-x^2-2x+3
y=-x%5E2-2x%2B3

y=-%28x%5E2%2B2x-3%29
y=-%28x%5E2%2B2x%2B1-1-3%29, completing the square
y=-%28%28x%2B1%29%5E2%2B4%29
-
highlight%28a=-1%29
vertex is point (-1,4).

The roots or zeros:
-%28x%2B1%29%5E2%2B4=0
%28x%2B1%29=0%2B-+2
x=-1-2, and x=-1%2B2
ZEROS -3 and +1.

You should be able to do the rest.
