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

What are we if not a collection of stories? From birth we are impressed by the stories of others till one day we start to gossip‚ complain about our day‚ sing songs‚ write novels‚ direct films‚ and string them together our own experiences to form a narrative. In Graeme Turner’s Film Narrative he presents the argument of Lévi-Struass‚ that narrative itself is used to frame our understanding of the world through the use of two opposing opposites to structure the story and can be proven by its reflection

want to purchase goods or services. An example of how I use money as a medium of exchange is simple. Every week when I do my grocery shopping‚ I give the cashier money‚ whether it is in the form of cash‚ or debit card‚ in exchange for groceries. Money as a unit of account is the yardstick people use to post prices and record debt. When we want to measure and record economic value‚ we use money as the unit of account. The unit of account function of money refers to the fact that the prices of different

to divide (Weinberg 2014). P53 is considered the “guardian of the genome” due to its variety of functions that are crucial for regular cell life cycles‚ and can prevent cancer (Weinberg 2014). Some of the functions of p53 include regulation of apoptosis‚ inducing cell-growth arrest‚ and activation of DNA repair proteins when the cellular DNA is damaged (Weinberg). Due to the majority of these functions preventing cancer and protecting the genome‚ one can see where the title “guardian of the genome”
