Domain and Range Practice

Which relation is not a function?

• (1,4) (6,8) (7,2) (3,10)

• (2,0) (4,7) (2,6) (3,9)

• (3,5) (1,5) (2,9) (6,1)

• (1,9) (17,7) (0,6) (7,2)

CCSS.HSF.IF.A.1

Assume this table represents someone selling pencils. What is a reasonable domain?

• 0<x<50

• all real numbers

• 1<x<11

• 2<x<15

Create a linear function of the table.

• f(x)=1x+2

• f(x)=3x+2

• f(x)=1x+3

• f(x) = 3x -1
