A rational function is the quotient of two polynomial functions.
Zeros and factors are closely related in polynomial functions. A zero of a polynomial is a value of the variable that makes the polynomial equal to zero, while a factor is a polynomial that divides another polynomial without leaving a remainder. If ( x = r ) is a zero of a polynomial ( P(x) ), then ( (x - r) ) is a factor of ( P(x) ). Thus, finding the zeros of a polynomial is equivalent to identifying its factors.
A power function is of the form xa where a is a real number. A polynomial function is of the form anxn + an-1xn-1 + ... + a1x + a0 for some positive integer n, and all the ai are real constants.
A power function is a specific type of mathematical function defined by the form ( f(x) = kx^n ), where ( k ) is a constant and ( n ) is a real number. In contrast, a polynomial function is a more general type of function that can be expressed as a sum of power functions with non-negative integer exponents, typically written as ( f(x) = a_nx^n + a_{n-1}x^{n-1} + \ldots + a_1x + a_0 ). Thus, while all power functions are polynomial functions (when ( n ) is a non-negative integer), not all polynomial functions are power functions, as they can contain multiple terms with different powers.
Substitute that value of the variable and evaluate the polynomial.
Yes, all polynomial functions are continuous.
In the 1880s, Poincaré created functions which give the solution to the order polynomial equation to the order of the polynomial equation
None, except that they are functions of one or more variables.

1 2 3 and 4 are 4 numbers, they are not functions of any sort - cubic polynomial or otherwise.
No, log n is not considered a polynomial function. It is a logarithmic function, which grows at a slower rate than polynomial functions.
A rational function is the quotient of two polynomial functions.
That's the definition of a "rational function". You simply divide a polynomial by another polynomial. The result is called a "rational function".
A device that was designed to tabulate polynomial functions
To factorize a third degree polynomial you need to find the common factor and then group the common terms in order to solve. If no common factor, find the first factor and it becomes a matter of trial and error. The easiest way to do this is to use a graphing calculator.
Rational functions and polynomial functions both involve expressions made up of variables raised to non-negative integer powers. They can have similar shapes and behaviors, particularly in their graphs, where they may exhibit similar end behavior as the degree of the polynomial increases. Additionally, both types of functions can be manipulated algebraically using addition, subtraction, multiplication, and division, although rational functions can include asymptotes due to division by zero, which polynomial functions do not have. Both functions can also be analyzed using techniques such as factoring and finding roots.
