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 rational function is the quotient of two polynomial functions.
Such functions are defined as one polynomial divided by another polynomial. Their properties include that they are defined at all points, except when the denominator is zero. Also, such functions are continuous at all points where they are defined; and all their derivatives exist at any point where they are defined.For more details, I suggest you read the Wikipedia article - or some other source - on "Rational function".
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.
As with most advanced math, if your "real life" involves engineering work, you will use such math; otherwise, you will hardly have anything to do, in this case, with polynomial functions.
Substitute that value of the variable and evaluate the polynomial.
Yes, all polynomial functions are continuous.
That depends on what you mean with "real-life". You won't need polynomial functions to sell stuff at a supermarket, or to cut off a dead branch from your tree... but if you work in science and engineering, you will need some really advanced math - much more than a simple polynomial function.
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.
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.

1 2 3 and 4 are 4 numbers, they are not functions of any sort - cubic polynomial or otherwise.
A rational function is the quotient of two polynomial functions.
No, log n is not considered a polynomial function. It is a logarithmic function, which grows at a slower rate than polynomial functions.
A device that was designed to tabulate 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".
