Quadratics #3: Understanding Vertex Form

What does the vertex form of a quadratic equation help us easily identify?

• The coefficients of the equation

• The degree of the polynomial

• The vertex of the parabola

• The roots of the equation

Which of the following is not a form of a quadratic equation?

• Linear form

• Factored form

• Standard form

• Vertex form

What is the correct vertex form of a quadratic equation?

• y = ax^2 + bx + c

• y = a(x - h)^2 + k

• y = ax^2 + k

• y = a(x + h) + k

In the vertex form of a quadratic equation, what does 'H' represent in the vertex (H, K)?

• x-coordinate of the vertex

• y-coordinate of the vertex

• Constant term

• Coefficient of x

If the vertex form of the equation is given and H is -2, what is the correct form of x in the equation?

• x - (-2)

• x + (-2)

• x + 2

• x - 2

If the vertex of a quadratic equation is (2, 1), what are the values of H and K?

• H = 2, K = 1

• H = 1, K = 2

• H = -2, K = -1

• (1, 4)

• (-1, -4)

• (4, -1)

• (-4, 1)

If 'a' in the vertex form of a quadratic equation is positive, what does the vertex represent?

• A maximum point

• A minimum point

• A point of inflection

• A neutral point
