- a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
- Example
- For Example f(x) = 3x² +7, find f (-3)f(-3) = 3(-3)² +7 f(-3) = 3(9) +7 f(-3) = 27+7 = 34 f(-3)=34
- Try this!
- Conclusion
- f(x) =2x -4, find f(5)
- Participation
- f(x) = 2x - 4, find f(5)f(5) = 2(5) -4 f(5) = 10 -4 = 6 f(5) = 6
- WOW! Very good, Ms, Rochelle!
