Graphing a quadratic with reflection and vertical stretch

The video tutorial covers graphing quadratic functions, focusing on the parabola's vertex form. It explains how to identify the vertex and axis of symmetry, and how the coefficient A affects the graph's orientation and compression. The tutorial also demonstrates checking points on the graph and reflecting them across the axis of symmetry.

What is the shape of the graph of a quadratic function like y = X^2?

• V-shape

• Circular

• U-shape

• Linear

In vertex form, what do the variables H and K represent?

• The axis of symmetry and slope

• The vertex coordinates

• The x-intercept and y-intercept

• The slope and y-intercept

What happens to the graph of a parabola when the coefficient 'A' is less than zero?

• It opens upwards

• It becomes a straight line

• It opens downwards

• It becomes a circle

What effect does a horizontal compression have on the graph of a parabola?

• It stretches the graph vertically

• It compresses the graph horizontally

• It shifts the graph upwards

• It shifts the graph downwards

How can you verify the accuracy of plotted points on a parabola?

• By measuring the distance between points

• By checking the slope

• By using a calculator

• By plugging in points into the equation

What is the purpose of reflecting points across the axis of symmetry?

• To determine the vertex

• To ensure the graph is symmetrical

• To find the slope

• To calculate the y-intercept

What is the final step in graphing a parabola using vertex form?

• Calculating the slope

• Reflecting points across the axis of symmetry

• Drawing the axis of symmetry

• Finding the y-intercept
