1. SECONDARY MATH 3 4-2COMPARING FUNCTIONS AND DOMAIN

2. WARM UP

3. TO COMPARE FUNCTIONS: Determine the key features of each function including: –Intercepts –Intervals of decreasing and increasing –maximums and minimums –Domain and range –End behavior Discuss the characteristics they have in common and their differences.

4. EXAMPLE #1

5. Function B

6. Similarities: Differences:

7. EXAMPLE #2 Function A – these are points on a continuous graph

8. EXAMPLE #2 Function B

9. Similarities: Differences:

10. DOMAIN: The set of all x-values defined by a function

11. 1. Find any values for which the function is undefined. 2. Write the domain in interval notation.

12. FIND THE DOMAIN FOR: 1.Find all the values for which the function is undefined. 1.Write the domain in interval notation.

13. 1. Find all the values for which the function is undefined. 2. Write the domain in interval notation.

14. FINDING THE DOMAIN

15. 1.Write a function for the volume. 2.Find all the values that would make sense. 3.Write the domain in interval notation.
