1. Teacher Heraldine Labiaga BARTOLOME AND MANUELA PAÑARES MEMORIAL NATIONAL HIGH SCHOOL SENIOR HIGH SCHOOL DEPARTMENT

2. General Mathematics Course Outline Chapter 1. Functions and their Graphs Function: An Introduction Piecewise- Defined Function Evaluating functions Operations on functions

3. WHAT WE ARE ABOUT TO LEARN? Identify functions from relations Evaluates a function Represents real-life situations using functions, including piece- wise functions

4. Chapter 1. General Mathematics Let’s have a Review!!! Operations on Functions All students must answer.

5. 3+4 =

6. 5+ -8=

7. -4 -3 =

8. 7- -5 =

9. (3)(-6) =

10. (-5)(-3) =

11. (15 3) =  

12. FUNCTIONS Functions relate an input to an output Functions in real life: Output: Score in the test Input: Number of hours studied

13. -9+ 4=

14. 18+ -2=

15. -4 - 6 =

16. 10 - 6 =

17. (-20)(2) =

18. (20 ) =
