To find if one is a function, you must see if the pattern is the same.
Domains (x) can not have two values
I forget what the y value is called, but there can be the same y- value for multiple x - values
A. is not a function, because its ordered pairs are all over the place, and the value 4 in the x - value has two values assigned - 0 and 3, which makes it invalid.
B. may be a linear function. Its ordered pairs aren't jumping all over the place.
Both the x and y go up one for one, so the function could be y = x + 3
C. isn't because the x - value 2 has two values. Again, that makes this invalid.
D. is invalid because there is two x - values for 2.
Therefore, the answer is B.

Step-by-step explanation:
hahaha
The expression we have is:

And we are given some values for x and y:

The first step will be to substitute the given values into the expression:

The next step is to solve 4^2 which is equal to 16:

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

Solving this final multiplication we get the result:
