If the original polynomial represents a position as a function of time, differentiating once will give you the speed, differentiating once more, acceleration. Differentiating a third time will give you the rate of change of acceleration; this is sometimes used, though not very frequently.
One application where different functions are differentiated not just three times, but an arbitrary number of times, is to evaluate the function value, using Taylor's method.
No. It simplifies to a monomial.
No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).
An example of a polynomial with 3 terms is 3x3 + 4x + 20, because there are 3 different degrees of x in the polynomial.
Yes! Also, 0 is a polynomial.
No. A polynomial can have as many degrees as you like.
It is a polynomial if the square root is in a coefficient but not if it is applied to the variable. A polynomial can have only integer powers of the variable. Thus: sqrt(2)*x3 + 4*x + 3 is a polynomial expression but 2*x3 + 4*sqrt(x) + 3 is not.
A "root" of a polynomial is any value which, when replaced for the variable, results in the polynomial evaluating to zero. For example, in the polynomial x2 - 9, if you replace "x" by 3, or by -3, the resulting expression is equal to zero.
The smallest is 0: the polynomial p(x) = 3, for example.
Since the question did not specify a rational polynomial, the answer is a polynomial of degree 3.
It is a numerical constant.
