How to graph a quadratic using a table

The video tutorial covers the concept of the axis of symmetry in quadratic functions, explaining how to calculate it using the formula X = -b/2a. It then guides viewers through plotting a graph by determining the vertex and selecting points to plot. Finally, it discusses how to determine the domain and range of the function, emphasizing that the domain is all real numbers while the range is limited by the vertex.

What is the formula for finding the axis of symmetry in a quadratic equation?

• X = -2a/b

• X = -b/2a

• X = b/2a

• X = 2a/b

When plotting a parabola, what is the first point you should determine?

• The vertex

• A random point on the graph

• The axis of symmetry

• The Y-intercept

Which of the following points is typically used to find the Y-intercept of a parabola?

• The point where Y = 0

• The axis of symmetry

• The point where X = 0

• The vertex

How does the axis of symmetry help in graphing a parabola?

• It determines the Y-intercept

• It provides the maximum value

• It is used to find the domain

• It helps in reflecting the graph

What happens to the graph of a parabola when you reflect it over the axis of symmetry?

• It shifts upwards

• It shifts downwards

• It becomes a straight line

• It mirrors itself

What is the domain of a quadratic function?

• Numbers between -1 and 1

• All real numbers

• Only positive numbers

• Only negative numbers

What is the range of a parabola that opens upwards with a vertex at (-2, -5)?

• From -infinity to infinity

• All real numbers

• From -5 to infinity

• From -infinity to 5
