Answer:

below the x-axis

Step-by-step explanation:

y=x^2+2x-3

the vertex is located on the axis of symmetry

to find h ax^2 +bx+c

h= -b/2a = -2/2(1) = -1

the x coordinate of the vertex is -1

to find the y coordinate, substitute into the equation

y = (-1)^2 +2(-1) -3

= 1-2-3

= -4

(-1,-4)

the vertex is below the x axis
