SCRIPT_WARM UP RULE: Dividing into three groups. We will give you 30s to name ur group (5-6 people in group) 5 person from the group will stand into the queue. The first person from one group will see a sentence which is written in the paper (5 seconds) and you have to read it to the next person. The last person hear it will have 10 seconds for thinking and after that the last person will go to the board and write down the sentence. It has 5 sentences. If your team get the sentence

college of accountants was organized with power to regulate entry into the field. Along with the development of modern accounting, a stereotypical image of the accountant was developed, because of its task being routine and purity mathematical in function. The accountant is view as a dull person that is chain to his desk all day. A survey of college students proved that accounting is treated with mental formulaic concepts, thus it has a stereotype image. Accounting may be defined as an information

that represents a function with the given range. Write your answers as ordered pairs. a) { (0 , 11) , (1 , 20) , (2 , 34) , (3 , 41) } this is because no value is same for the order pairs in x values b)Create and justify a relation that does not represent a function with the given range. Write your answers as ordered pairs. { (0 , 11) , (0 , 20) , (2 , 34) , (3 , 41) } this is the case since the values of X in the first two cases are similar hence making it not be a function 2) Find the equation

Stewart Calculus ET 5e 0534393217;1. Functions and Models; 1.1 Four Ways to Represent a Function 1. (a) The point ( 1, 2 ) is on the graph of f , so f ( 1)= 2 . (b) When x=2 , y is about 2.8 , so f (2) 2.8 . (c) f (x)=2 is equivalent to y=2 . When y=2 , we have x= 3 and x=1 . (d) Reasonable estimates for x when y=0 are x= 2.5 and x=0.3 . (e) The domain of f consists of all x values on the graph of f . For this function, the domain is 3 x 3 , or 3,3 . The range of f consists of all y values

In testing phase, the test image is the LR input image Y, obtained from TV decomposition technique. The LR input image Y is upsampled by the necessary scaling factor s. Form the overlapping patches P for upsampled image and convert them into vector to minimize the artifacts. The sparse representation of the LR input image αs can be obtained using the LR input patches P and the trained LR dictionary as input to the OMP algorithm. The trained HR dictionary D_il is updated by αs to obtain the updated
