Label the vertex of a parabola with b

The video tutorial explains the effects of negative values on reflections across the X and Y axes, focusing on the role of 'B' in equations. It discusses two methods for solving equations: setting them to zero and factoring out 'B'. The tutorial emphasizes understanding transformations to find the vertex and clarifies the confusion often caused by 'B'. It also touches on graphing and the impact of compression, highlighting the importance of identifying the vertex without focusing on the graph's shape.

What happens to the graph of a quadratic equation when 'a' is negative?

• It shifts upwards.

• It reflects across the Y-axis.

• It shifts downwards.

• It reflects across the X-axis.

How does a negative 'b' affect the graph of a quadratic equation?

• It reflects across the X-axis.

• It stretches the graph vertically.

• It compresses the graph horizontally.

• It reflects across the Y-axis.

What is one method to simplify finding the vertex of a quadratic equation with 'b'?

• Ignore 'b' completely.

• Multiply the equation by 'b'.

• Add 'b' to both sides.

• Set the equation to zero.

Why is factoring out 'b' important in quadratic equations?

• It eliminates the need for solving the equation.

• It makes identifying the vertex clearer.

• It simplifies the equation for easier graphing.

• It helps in finding the Y-intercept.

Does the vertex of a quadratic equation change with horizontal compression?

• Yes, it moves to the left.

• Yes, it moves upwards.

• Yes, it moves to the right.

• No, it remains the same.
