Hey there!
The answers to your question are C, D, and E
If there are repeats in the X column, then it's not a function. If there are no repeats, then it is! If there are repeats in the Y column, that's ok, but there cannot be repeats in the X column.
Hope this helps! If you need any other help, just tell me!

Answer:
122 1/4
Step-by-step explanation:
Hope this helps! :)
(12x12) 12x 
x12) / (3/2 x3/2)
PEMDAS = parathesis exponents multiplictation division add subtract.
12x12=24
3/2x3/2=9/4
12x2/3=8x12=96
so 24+96=120
9/4 can be like 4x2=8 so i remaing
120+2=122 1/4?
The sequence is, in fact, quadratic. It is described by the equation
.. a[n] = (n*(n -1))/2 +2
First differences are increasing, so the sequence will not be arithmetic. An arithmetic sequence has constant first differences.
Second differences are constant, so the sequence will not be geometric. A geometric sequence will have first-, second-, third-differences, and those to any level, that have the same constant ratio as the terms of the original sequence.
