What is the RANGE of the function?

• All Real Numbers

• y ≤ 4

• y < 4

• 0 < y < 4

Which graph matches:

-x+4 if x < 2

2x-6 if x ≥ 2

• A

• B

• C

• D

 $f\left(x\right)=\ x^{2\ }-\ 4;\ Find\ f\left(6\right)$  

• 40

• -40

• 32

• -32

f(1) =

• -2

• -1

• 0

• 1

• 2

What is g(7) if:

• -17
• -13 
• 13       
• 17

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)}

What is the Domain of this linear function?

• -3 < x ≤ 5
• x = -1
• 5 < x ≤ -3
• -2 < x ≤ 6

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.

Identify the domain of the following relation:

• {-6, 14, 2, 28}
• {(-6,14), (0,32), (2,38), (4,44)}
• {-6, 0, 2, 4}
• {14, 32, 38, 44}
