A. Use these points for questions 1 and 2: {(6, -6), (2, 2), (0, 8), (5, 2), (-5, 2)}

1. What are the domain and range?

2. Is the relation a function? Explain why or why not.

B. Use these points for questions 3 and 4: {(-24, -14), (-9, -14), (13, -83), (-21, -83), (-9, -14), (13, -13)}

3. What are the domain and range?

4. Is the relation a function? Explain why or why not.

C. State the domain and range: Use the grid to draw the graph and verify your answer. Be sure to label the scales on your axes to accommodate the numbers in the problem. (You may not use a computer program to draw the graphs for you. The goal is to understand how to select points to draw a graph.)

5. y = x^2 + 86

6. y = 2x^3 + 8

7. y = 40 - 8x^2

D. Find the following showing the steps as done in the lesson content.

8. f(x) = 11x - 5x^2 + 4, find f(-4)

9. f(x) = 7 - 5x + 7x^2, find f(-9a)

10. f(x) = (x-2)^2 -15, find f(y-3)
