Unit 3 Test - Graphing Linear Functions

(3.1)What is the range of the following relation: (9, -2) (4, 3)  ( 8, 10) ( -4, 8)

• {-4, 4, 8, 9}

• {-2, 3, 8, 10}

• {(9, -2) ( 4, 3)}

• {(8, 10) (-4, 8)}

(3.1) Find the RANGE

• {-5, -2, 1, 4}

• {-1, 0, 2, 3}

(3.1)

• Function because there are two x values of 18 and 6 with different y values.

• Not a Function because the input 6 and 18 both have different output values.

(3.1)

• Function, because a horizontal line would cross two points at y = 1.

• Not a Function, because a vertical line would cross two points at x=2.

(3.1)

• Function

• Not a Function because the input on the left has two outputs on the right.
