Please answer each of the following questions using the Exploring Vertex Form classwork and your

notes.

Vertex Form:

Quadratic parent function:

1) All of the functions you worked with in the classwork are called quadratics. What did all the

quadratics have in common?

2) The graphs of these functions are called parabolas. How would you describe a parabola to

someone who has never seen one?

3) How can you identify the vertex of a parabola without graphing it if its equation is given in

vertex form?

4) How can you identify the line of symmetry of a parabola without graphing it if its equation is

given in vertex form?

5) Why do you think the graph of a quadratic is symmetric?

6) How could you tell if a graph opens up or down by examining the equation?

7) How could you identify the width of the graph in reference to the parent function by examining

the equation?

8) Describe what effect each of the following has on the graph:

a: ___________________________________

h: ___________________________________

k: ___________________________________

9) Why do you think the graph of a quadratic is curved instead of linear?
