Understanding Quadratic Functions

What is the y-intercept of a quadratic function?

• The point where the graph is symmetrical

• The point where the graph intersects the y-axis

• The point where the graph intersects the x-axis

• The maximum point of the graph

What are the x-intercepts of a quadratic function?

• The highest point of the graph

• The points showing maximum curvature

• Points where the graph touches or crosses the y-axis

• Points where the graph touches or crosses the x-axis

What defines the vertex of a quadratic function's graph?

• The intersection point on the y-axis

• The point that defines the minimum or maximum of the graph

• The center point of the graph

• The intersection points on the x-axis

What shape does the graph of a quadratic function form?

• A 'u'-shaped curve

• A straight line

• A circle

• An 'n'-shaped curve

What is the line of symmetry in a quadratic function's graph?

• A vertical line that divides the graph into two mirror images

• A horizontal line under the graph

• A curved line following the graph

• A diagonal line across the graph

How many points are typically used to graph a quadratic function effectively?

• Six points

• Two points

• Three points

• Five points

What is the significance of the vertex in the graph of a quadratic function?

• It is where the function crosses the x-axis

• It is where the function crosses the y-axis

• It represents the maximum or minimum value of the function

• It indicates the end points of the graph

Which method is not a typical way to solve a quadratic equation?

• Graphing

• Completing the square

• Using a pie chart

• Using the quadratic formula
