Answer: D, neither A nor B
Step-by-step explanation: In a function, the x (the input) cannot repeat in the given set of ordered pairs. In Set A, 2 repeats in the third and fourth ordered pairs. In Set B, 9 repeats in the third and fourth ordered pairs as well.

Answer:
C
Step-by-step explanation:
A closed circle means inclusive, and -2 is included in values that would make the equation true. Then you just have to test another number greater than and less than -2 to see which way the arrow should point.
-3(-3) + 1 < 7
9 + 1 < 7
10 < 7 FALSE
-3(0) + 1 < 7
1 < 7 TRUE
All values (including -2) will make this equation true
Answer:
x=3+2×sqrt(3)
x=3-2×sqrt(3)
Step-by-step explanation:
2(x-3)²-24=0
2(x-3)²=24
(x-3)²=12
Case 1:
x-3=sqrt(12)=2×sqrt(3)
x=3+2×sqrt(3)
Case 2:
x-3=-sqrt(12)=-2×sqrt(3)
x=3-2×sqrt(3)
