Graphing Quadratic Functions

This lesson teaches how to graph quadratic functions using their zeros. It explains the symmetry of parabolas, the significance of intercepts, and how to use factored forms to find zeros. The lesson also covers constructing graphs using symmetry and discusses perfect squares in quadratic functions.

What is the line of symmetry for a parabola?

• A horizontal line

• A vertical line

• A diagonal line

• A curved line

What does the zero of a quadratic function represent in the context of a square's area?

• The volume of the square

• The perimeter of the square

• The diagonal of the square

• The side length that makes the area zero

How can the graph of F(x) = x^2 be described?

• A parabola

• A circle

• A hyperbola

• A straight line

What is the significance of the factored form of a polynomial?

• It changes the degree of the polynomial

• It helps in finding the zeros of the function

• It simplifies the polynomial

• It makes the polynomial non-factorable

What is the x-intercept of the function F(x) = (x + 3)^2?

• 6

• 0

• 3

• -3

What is a characteristic of polynomials that can be factored into perfect squares?

• They have infinite zeros

• They have only one zero

• They have multiple zeros

• They have no zeros

Where is the vertex located in a perfect square polynomial?

• At the origin

• On the y-axis

• On the x-axis

• At infinity
