If the x value is repeated is is not a function. (unless it is a negative and a positive)
So lets see:
For A we have 3 6 9 12 no repeations so therefore It is A
For B we have 2 2 3 9, 2 is repeated so therefore it is B
For C we have 4 6 4 6, both 4 and 6 were repeated so therefore is is B
and lastly for D we have 3 5 6 6
And 6 was repeated so therefore it is B.
A)A
B)B
C)B
D)B

Please help!! I'll give 30 points and brainliest.
Valentin [98]

Step-by-step explanation:

3 + \frac{9}{4} = \frac{9}{x+4} \\  \\  \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\  \\ \therefore \:21(x + 4) = 36 \\  \\ \therefore \:21x + 84 = 36\\  \\ \therefore \:21x = 36 - 84\\  \\ \therefore \:21x = - 48\\  \\  \therefore \:x =  \frac{-48}{21} \\  \\ \therefore \:x =  \frac{-16}{7} \\  \\  \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\  \\
