The video tutorial explains how to graph a quadratic equation using vertex form. It covers the components of vertex form, including the values of a, h, and k, and how they affect the graph's transformations. The tutorial demonstrates how to shift the graph horizontally and vertically, and how to determine the vertex and axis of symmetry. It also discusses the behavior of the graph when the value of a changes, using a table of values to illustrate the effects. The video concludes with a brief discussion on intercepts and end behavior, noting that the graph does not cross the x-axis.

What is the effect of the 'a' value being less than 1 in the vertex form of a quadratic equation?

• The graph becomes narrower.

• The graph becomes wider.

• The graph shifts downwards.

• The graph shifts to the left.

How does the 'h' value in the vertex form affect the graph of a quadratic equation?

• It shifts the graph upwards.

• It shifts the graph downwards.

• It shifts the graph to the left.

• It shifts the graph to the right.

What is the axis of symmetry for the equation y = 1/2 * X - 3^2 + 2?

• X = -3

• X = 0

• X = 3

• X = 2

When comparing y = X^2 and y = 1/2 X^2, what is the primary difference in their graphs?

• The graph of y = 1/2 X^2 is shifted upwards.

• The graph of y = 1/2 X^2 is shifted downwards.

• The graph of y = 1/2 X^2 is wider.

• The graph of y = 1/2 X^2 is narrower.

Why does the graph of y = 1/2 * X - 3^2 + 2 not have any real x-intercepts?

• The graph is a horizontal line.

• The graph intersects the y-axis only.

• The graph is entirely below the x-axis.

• The graph is entirely above the x-axis.
