Question

find the vertex and the parabola: f(x)=-x^2-2x+3

Answer 1

*of the parabola

Answer 2

the vertex is when x = -b/2a

Answer 3

--2/2.1 = 2/2 = 1

(1,y)... -1-2+3=0

(1,0) is the vertex

Answer 4

i think that typoed...

Answer 5

--2/2.-1 = 2/-2 = -1

Answer 6

(-1,y)...-1+2+3 = 4

(-1,4)

Answer 7

vertex is (-1,4)

Answer 8

you could always write it in vertex form
f(x)=-(x^2+2x)+3=-(x^2+2x+1)+3+1=-(x+1)^2+4
vertex is (-1,4)
