What do I have to know to graph a quadratic in standard form

The video tutorial explains how to graph quadratic equations in standard form. It covers the shape of parabolas, the importance of the vertex, and the axis of symmetry. The tutorial also demonstrates how to evaluate points on the graph and discusses the end behavior of parabolas.

What is the shape of the graph of a quadratic equation in standard form?

• A straight line

• An ellipse

• A circle

• A parabola

What is the axis of symmetry in a quadratic graph?

• A horizontal line

• A diagonal line

• A vertical line

• A curved line

How do you find the axis of symmetry for a quadratic equation in standard form?

• X = A / 2B

• X = -A / 2B

• X = B / 2A

• X = -B / 2A

What is the purpose of evaluating points when graphing a quadratic equation?

• To find the slope of the line

• To determine the y-intercept

• To identify points that lie on the graph

• To calculate the area under the curve

When creating a table of values for a quadratic graph, what should you do after finding the axis of symmetry?

• Calculate the slope

• Choose points to the left of the axis

• Find the y-intercept

• Determine the maximum value

How do you find the y-coordinate of the vertex in a quadratic equation?

• By using the formula y = -B / 2A

• By substituting the x-coordinate into the equation

• By finding the midpoint of the parabola

• By calculating the average of the roots

What is the end behavior of a parabola?

• It intersects the x-axis at two points

• It forms a closed loop

• It extends indefinitely

• It stops at the vertex
