Determine whether the function is linear, constant, or neither

Question

y = x3 - x2 + 8

a. Linear

b. Constant

c. Neither
I think it is neither

Answer 1

If t were linear it would be of form
y = m x + b
if it were constant it would be of form
y = b
it is in fact a cubic polynomial.
By the way we usually write exponents as:
y = x^3 - x^2 + 8
