1. Do now Complete the table below given the domain {-1, 0, 1, 2} X
Y= -4x - 3
Show work!! Y
(x,y) -1
Y= -4(-1) - 3
Y= 4 - 3
Y= 1 1
(-1, 1) -7
(2, -11)

2. Linear or Nonlinear Functions

3. INVERSE of a RELATION SWITCH THE X AND Y!!!!!! (3, -4) becomes (-4, 3)
Find the inverse of the following relation:
(2, -5), (4, 3), (6, -2), (8, 9), (-3, -4)

4. Linear Functions
Linear Functions have graphs that are straight lines and represent constant rate of change.

5. NonLinear Functions
Nonlinear Functions have graphs that are not straight lines.
The rate of change is not constant (values don’t increase/decrease at the same rate).

6. Linear or Nonlinear?

7. Linear or Nonlinear?

8. Linear or Nonlinear?

9. Linear or Nonlinear?

12. Linear
Nonlinear

15. Exit ticket 1. What does linear mean?
2. Is the function linear or nonlinear? WHY OR WHY NOT? A B X Y 1 6 2 8 3 10 4 12 X Y -2 2 -1 4 8 1 16
