How to graph a quadratic equation in standard form

This video tutorial explains how to graph quadratic equations in standard form. It covers identifying the axis of symmetry, determining the vertex, understanding the graph's opening direction, and plotting additional points using axis symmetry. The tutorial provides a step-by-step guide to ensure accurate graphing of quadratic functions.

What is the formula used to find the axis of symmetry in a quadratic equation in standard form?

• X = B / 2A

• X = -B / 2A

• X = A / 2B

• X = -A / 2B

How do you determine the X-coordinate of the vertex of a quadratic function?

• By finding the midpoint of the parabola

• By using the Y-intercept

• By calculating the slope

• By using the axis of symmetry

What does the vertex of a parabola represent in a quadratic function?

• The point where the graph intersects the X-axis

• The highest or lowest point on the graph

• The point where the graph intersects the Y-axis

• The midpoint of the graph

How can you determine the direction in which a parabola opens?

• By checking the sign of the A coefficient

• By checking the sign of the B coefficient

• By checking the sign of the C coefficient

• By checking the value of the vertex

What is the purpose of plotting additional points when graphing a quadratic function?

• To complete the graph by reflecting over the axis of symmetry

• To determine the axis of symmetry

• To find the Y-intercept

• To calculate the slope
