I need help answering these questions

1.A vertex is the very tip of a parabola either negative or positive.

To find the vertex of an equation that is in standard form first you must get the equation in the form y = ax2 + bx + c. Then calculate -b / 2a. This is the x-coordinate of the vertex. To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
