Quadratic Graphs - Part 2

This video tutorial explains the properties of quadratic equations, including X and Y intercepts, graph shapes, and turning points. It covers how to find the axis of symmetry and the coordinates of turning points using formulas. The tutorial also guides viewers on sketching quadratic graphs by combining knowledge of intercepts, shapes, and turning points.

What does a positive X squared term indicate about the shape of a quadratic graph?

• A smiley U shape

• A sad N shape

• A straight line

• A circle

What is the axis of symmetry in a quadratic function?

• The line that divides the graph into two symmetrical halves

• The line where the graph intersects the Y-axis

• The lowest point on the graph

• The highest point on the graph

How can you find the X coordinate of the turning point in a quadratic equation?

• By calculating the roots

• By setting the equation to zero

• By using the formula -B/2A

• By finding the Y intercept

What is the next step after finding the X coordinate of the turning point to determine its Y coordinate?

• Find the derivative of the equation

• Use the X coordinate to find the Y intercept

• Substitute the X coordinate back into the original equation

• Calculate the average of the roots

Which of the following is NOT a step in sketching a quadratic graph?

• Determining the axis of symmetry

• Calculating the area under the curve

• Finding the turning point

• Identifying the X and Y intercepts
