Question

Where is the vertex of the parabola? y = x2 + 2x – 3 Above the x-axis Below the x-axis On the x-axis On the y-axis

Answer 1

Hint

\[\large Vertex = \frac{-b}{2a}\]

this will give you your x-value for the vertex...you can then plug that into your equation to solve for the 'y' value of the vertex as well
