HOw can I find the domain and range of this problem

Question

4x^3-39x^2+93.5

Answer 1

The domain of all polynomials is ℝ or all real numbers, or (-∞,∞).

The range depends on the polynomial. For odd degree polynomials (such as the present one), the range is also (-∞,∞).

For even degreed polynomials, there is an absolute maximum or absolute minimum.
