CHAPTER 4 : FUNCTIONS AND THEIR GRAPHS 4.1 Definition of Function A function from one set X to another set Y is a rule that assigns each element in X to one element in Y. 4.1.1 Notation If f denotes a function from X to Y‚ we write 4.1.2 Domain and range X is known as the domain of f and Y the range of f. (Note that domain and range are sets.) 4.1.3 Object and image If and ‚ then x and y are known respectively as the objects and images of f. We can write ‚ ‚ . We can represent

forget that the line has to be curved‚ having those extra points graphed will help remind you that the line will be curved. If you’re a value is positive‚ then the parabola will be a smile shape. If you’re a value is a negative‚ your parabola will be a sad face shape. In any and all functions‚ you have a trajectory‚ you start at a given spot and throw an object and measure the height and distance and out it on to a graph‚ the most common set up for a function like this is(ax^2+bx+c=0).

“How Does the Body Function?” Do you consider your body a delicate temple‚ and do you give any thoughts to the daily functions it provides for you? Well‚ to name a few‚ the eyes‚ ears and skin play a vital role in our lives‚ and without these precious body parts I believe our life of living free would be limited. Someone once said that “the eyes provide a window to the soul‚ they also provide us with a window to the world.” Our vision starts when you look at an object; the light from

What is Production Function? Definition and Explanation: ‚ Production of goods requires resources or inputs. These inputs are called factors of production named as land‚ labor‚ capital and organization. A rational producer is always interested that he should get the maximum output from the set of resources or inputs available to him. He would like to combine these inputs in a technical efficient manner so that he obtains maximum desired output of goods. The relationship between the inputs and

The left ventricle has a much thicker wall than the right ventricle because the left ventricle has to pump blood to the whole body while the right ventricle only has to pump blood to the lungs. 3.
