They are both polynomial functions. A quadratic is of order 2 while a cubic is of order 3.

A cubic MUST have a real root, a quadratic need not.

Is f(x)(x 2)(4-x) a quadratic function?

Yes, ( f(x) = x^2(4 - x) ) is a quadratic function. When expanded, it becomes ( f(x) = 4x^2 - x^3 ), which is a polynomial of degree 3. However, if we consider the term ( x^2(4 - x) ) without expansion, the leading term ( x^2 ) indicates it has a quadratic component, but the presence of ( -x^3 ) means it is not purely quadratic. Thus, it is a cubic function, not a quadratic one.


What are the similarities between quadratic function and cubic function?

Both quadratic and cubic functions are polynomial functions, meaning they can be expressed in the form of ( ax^n + bx^{n-1} + \ldots ) where ( a ) is a non-zero coefficient and ( n ) is a non-negative integer. They both exhibit smooth, continuous curves and can have real or complex roots. Additionally, both types of functions can model a variety of real-world phenomena and can be analyzed using similar techniques, such as finding their vertices, intercepts, and analyzing their behavior at infinity.

Can the sum of a cubic and a quadratic polynomial may have a degree different from 4?

The sum of a cubic and a quadratic is still a cubic.(ax3+ bx2+ cx + d) + (ex2+ fx + g) = ax3+ (b+e)x2+ (c+f)x + (d+g)Therefore, the result will always be different to a polynomial of degree 4.
