Definition
A quartic function is a polynomial function of degree four, meaning it has the highest exponent of 4. It can be written in the form f(x) = ax^4 + bx^3 + cx^2 + dx + e.
Coefficients are numbers multiplied by variables in a polynomial. In a quartic function, there are five coefficients (a, b, c, d, e) corresponding to each term.
