B
Because all of the other equations are in the linear format of y=mx+b while B has the extra 3 added on to it.
Hope this helps!!

Answer:

B

Explanation:

A C and D are all linear. The powers on x in all three questions is 1. For example the first answer could be written as y = 3x^1 - 4. C and D are much the same.

So if you are thinking that B must be the answer, you would be right. x is raised to the third power -- or I think that is what is intended. y = x^3 - 10
