Vertex Form of a Quadratic Function Flipbook Notes
Instructions: Create a flipbook by cutting out and pasting all questions and graphs.
1) Identify the vertex for each graph A, B, and C. What do you notice about each vertex of
the parabolas compared to the equations?
A.
B.
y = x2
C.
f(x) = (x – 3)2
y = (x + 2)2
2) Identify the vertex for each graph D, E, and F. What do you notice about each vertex of
the parabolas compared to the equations?
D.
E.
y = x2 + 3
F.
y = (x + 4)2 + 1
g(x) = (x – 1)2 – 3
3) Explain the rules to graphing a quadratic function using the vertex.
4) Name the vertices (plural for the word vertex): G. y = (x – 4)2
H. f(x) = (x + 3)2 – 5
5) Graph the following quadratic functions:
I. y = (x + 1)2
J. y = x2 – 4
K. h(x) = (x – 4)2 + 2
L. y = (x + 2)2 – 5
6) Make up your own quadratic function and have your partner graph the problem. Then grade
and correct the “test question.” Did your partner get an A? Why or why not?
EXTRA: What do you think happens when you put a negative in front of the function? Explain
and then graph y = -(x – 3)2 + 6.
