Respuesta :

Answer:

D

Step-by-step explanation:

D, because it's a polynomial equation.  This mean the value of y goes up by base factor for every x value.  Take for example, when x is 3, then y is 10.  Also, when x is 4, then y is 17.  Which mean x and y are not linear relationship, but more of an exponential relationship.
