Polynomial and rational functions can be used to model a wide variety of phenomena of science, technology, and everyday life.
Choose one of these sectors and give an example of a polynomial or rational function modeling a situation in that sector. [Hint: see the examples and exercises in the book....
A polynomial function is a function that can be communicated in the form of a polynomial.
The definition can be determined from the definition of a polynomial equation. A polynomial
is for the most part represented as P(x). The highest power of the variable of P(x)is known as
its degree. The degree of a polynomial function is exceptionally vital because it tells us about
the conduct of the function P(x) when x becomes exceptionally large. The domain of a
polynomial function is whole real numbers (R). If P(x) = an xn + an-1 xn-1+.……….…+a2 x2 +
a1 x + a0, then for x ≫ 0 or x ≪ 0, P(x) ≈ an xn. Therefore, polynomial functions approach
power functions for very large values of their variables. A polynomial function has only
positive integers as exponents. We can also execute various types of arithmetic operations for
such functions as addition, subtraction, multiplication, and division. x2+2x+1 = 0, 3x-7=2
and 7x3+x2-2=0 are some examples of polynomial functions (BYJU’s, 2020).
The polynomial function can be used in our everyday life especially when we visit the
supermarket. Let say we go to the supermarket to pick up a few groceries such as 2lbs rice,
2lbs chicken, 1 tomato, 1 onion, and 1 litre cooking oil. In constructing a simple polynomial
function I will be using ‘a’ to represent the price for rice, ‘b’ representing the price for
chicken, ‘m’ representing the price for tomato, ‘n’ representing the price for onion and ‘p’
