WRITING A FUNCTION RULE:

WRITE A FUNCTION RULE FROM THE TABLE: x F(x) 1 -1 2 0 3

WRITE A FUNCTION RULE FROM THE TABLE: x F(x) 1 -1 2 0 3 1 4 2

WRITE A FUNCTION RULE FROM THE TABLE: x F(x) 1 -1 2 0 3

WRITE A FUNCTION RULE FROM THE TABLE: x F(x) 1 -1 2 0 3 1 4 2 Ask yourself, “What can I do to 1 to get to -1, 2 to get to 0…. ?

WRITE A FUNCTION RULE FROM THE TABLE: x F(x) 1 -1 2 0 3

WRITE A FUNCTION RULE FROM THE TABLE: x F(x) 1 -1 2 0 3 1 4 2 Ask yourself, “What can I do to 1 to get to -1, 2 to get to 0…. ? Subtract 2 from each input value.
