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.]

Go to www.desmos.com/calculator, write your equation, or function, and develop your explanation using the properties of graphs.

In order join a tennis class , you pay a $200 annual fee, then $10 for each class you go to . What is the average cost per class if you go to 10 classes

In manufacturing a medical equipment, a firm incurs costs of two types. Fixed annual costs of $ 155,000 are incurred regardless of the number of units produced. In addition, each unit produced costs the firm $5. If C equals total annual cost in dollars and x equals the number of units produced during a year;
a) Develop the function C = f(x) which expresses annual cost.
b) Calculate f(280,000)? What does f(280,000) represent?
c) State the restricted domain and restricted range of the function if maximum production
capacity is 850,000 units per year

use long division to determine the quotient and remainder when f(x) = 4x³+6x²-2x+5 is divided by (2x-1)

use long division to find the quotient and the remainder when the function f(x) = x³+3x²-4 is divided by (x-1).hence factorize the function completely

Let a_1,a_2,a_3,a_4,a_5 be an arithmetic progression with common difference d such that cos d=sqrt{0,2}.Find cos^2a_3 given that tg a_1tg a_2+tg a_2tg a_3+tg a_3tg a_4+tg a_4tg a_5 = 16.
