A cubic function has highest power 3. So the cubic here is
f(x) = 5x^3 + 2x + 1.
(3x + 1 is linear, 3x^2 + x + 2 is quadratic, and x^3 + x^4 + 5 is degree 4 because of the x^4 term.)
f(x) = 5x^3 + 2x + 1.
(3x + 1 is linear, 3x^2 + x + 2 is quadratic, and x^3 + x^4 + 5 is degree 4 because of the x^4 term.)
