Matching functions & graphs without calculators

2. Write down as many facts about the graph & its function as you can in 2 minutes.

3. FACTS:

4. y = x2 – 4x – 6
Write down as many facts about the function & its graph as you can in 2 minutes.

5. Using the graphs: Identify THE GRAPHS THAT HAVE THE SAME VERTEX.
Identify the graphs with no roots & the graphs with ONE ROOT.
IDENTIFY THE GRAPHS THAT HAVE THE SAME ROOTS.
IDENTIFY THE GRAPHS THAT HAVE THE SAME Y-INTERCEPT.

6. y = x2 – 4x – 6
FACTS:

7. Using the function strips:
1). IDENTIFY THE FUNCTIONS WHOSE GRAPHS WOULD HAVE A Y-INTERCEPT OF 4.
2). IDENTIFY THE FUNCTIONS WHOSE GRAPHS WOULD OPEN UP.
3). IDENTIFY THE FUNCTIONS WHOSE VERTEX WOULD BE THE SAME AS THE Y-INTERCEPT.

8. Using graphs & functions:
MATCH THE GRAPHS & FUNCTIONS.
COMPLETE THE ANSWER SHEET & CREATION PROBLEM.

9. Using the graphs & function strips:
4). IDENTIFY THE FUNCTIONS THAT WILL HAVE THE ORIGIN AS ONE OF ITS ROOTS.
5). IDENTIFY THE FUNCTIONS WHOSE VERTEX HAS AN X-COORDINATE OF -1.

10. Using the graphs & functions:
Compare GRAPH J and equation #7.
-What is the value of the larger maximum?
-What is the DISTANCE BETWEEN in the y-intercepts?
Compare GRAPH B and equation #12.
-What is the value of the larger minimum?
-What is the DISTANCE BETWEEN the y-intercepts?
