In a quadratic equation, what does the vertex represent?

• The intersection with the x-axis

• The starting point of the graph

• The highest or lowest point of the parabola

• The midpoint of the parabola

Which formula is used to find the x-coordinate of the vertex?

• x = 2a / b

• x = b / 2a

• x = -2a / b

• x = -b / 2a

What is the next step after finding the x-coordinate of the vertex?

• Graph the equation

• Find the y-coordinate by substituting x back into the equation

• Calculate the slope

• Solve for the roots

What is the final form of the vertex in terms of coordinates?

• (x, y)

• [x, y]

• {x, y}
