Answer:
nonlinear
Step-by-step explanation:
In a linear equation, there are no multiplications of variables by variables.
x³ means x × x × x, so there is a multiplication of variables in the equation, and the equation is not linear.
Non-linear
Since one of the terms has an exponent of 3, this is a cubic equation, a third degree equation. It is a curve and therefore, NOT a linear equation.
