What do I need to know to graph a quadratic in vertex form

The video tutorial covers graphing quadratics in vertex form, explaining the vertex form equation, identifying the vertex, and understanding translations. It discusses the end behavior of graphs based on the value of 'a' and the parent graph of quadratics. The tutorial also covers evaluating points to plot graphs accurately.

What is the vertex form of a quadratic equation?

• y = a(x - h)^2 + k

• y = ax^2 + c

• y = ax^2 + bx + c

• y = a(x + h)^2 - k

In a parabola, what is the vertex?

• The midpoint of the parabola

• The lowest or highest point of the parabola

• The intersection with the x-axis

• The intersection with the y-axis

What does a translation in graphing involve?

• Reflecting the graph

• Shifting the graph in different directions

• Changing the shape of the graph

• Rotating the graph

How does the value of 'a' affect the end behavior of a quadratic graph?

• It determines the axis of symmetry

• It determines the vertex position

• It determines the direction the graph opens

• It determines the width of the graph

What is the parent graph of a quadratic function?

• y = 1/x

• y = x^2

• y = x^3

• y = x

Why is it important to evaluate points on a transformed graph?

• To determine the slope of the graph

• To determine the axis of symmetry

• To accurately plot the graph

• To find the exact position of the vertex

How can you evaluate points on a quadratic graph?

• By using the quadratic formula

• By using the midpoint formula

• By creating a table and plugging in values

• By finding the derivative
