A function of x means that you get an answer if you plug in a certain value for x.

A is not a function, because it specifies that x=5
B could be a function, but you'd have to rewrite it in a form y = ....
C is a nice function of x. Just swap it: y=x2
D is a circle. You can't rewrite it as a clean function of x.

So I would choose C.

Answer:

B) 2 + 4x = 5 - 3 - 3x

Step-by-step explanation:

By simplifying JUST the right side and re-arranging them

2 + 4x = 5 - 3(x + 1),

2 + 4x = 5 - 3x -3,

2 + 4x = 5 -3 - 3x
