Parabolic Problems

By Altum Spectent

Another problem I have seen lately is that of parabolas and symmetry, as well as that of intervals, domains, ranges, and other graphical dilemmas. If one is asked to define the interval over which a function is increasing, decreasing, or remaining the same, the answer is always (x 1 , x 2 ). One never uses brackets when referring to an interval! However, if one is asked to define a domain or range, the answer could include one or more brackets: (x 1 , x 2 ], [x 1 , x 2 ), or [x 1 , x 2 ] if referring to the domain; (y 1 , y 2 ], [y 1 , y 2 ), or [y 1 , y 2 ] if referring to the range. (x 1 , x 2 ) and (y 1 , y 2 ) can also be used to describe the domain and range, respectively, in some cases. A function is said to be increasing if the y-values are getting larger, decreasing if they are getting smaller, and constant if they are remaining steady. The domain of the function is the entire group of all the x -values for which the function is continuous, while the range is the entire ...

Essay Writing Tips

By Anonymous
When a professor assigns any type of paper, the first response for many is, "Oh, no! I can't do this! How many pages again?" This, however, is not the way to think, as this will lead students to feel overwhelmed—that the paper will be impossible to write. Instead, the thought should be, "What can I write about? What am I interested in?" Then, once a topic is chosen, one shouldn't look at the whole—look at the parts: the introduction, the body, the conclusion; the paragraphs, the sentences, the words. If a good sentence is written, with appropriate words, sentence structure, and tense, then the only thing to do is make sure the same tense is used throughout the paper, and that words, sentence structures, and sentence lengths are not overused. When this system is followed, it renders the writing process much easier, and less overwhelming. Once the paper is finished, the results can sometimes even surprise the author! To summarize: Look at the ...

Systems of Linear Equations

I'm back! Sorry for the tardiness, but college students never have much extra time on their hands. Anyway, today's post will be a mathematical review; coming directly from a recent tutoring session in which I helped a student with  systems of linear equations . Systems of linear equations can be solved by using either the substitution method, the addition method, or the graphical method. Sometimes more than one method is required, especially for systems of three equations, each with the same three variables. Personally, I prefer the addition and substitution methods, but the graphical method is fine, too. Say we are given the following system of linear equations: This is very simple and straightfor ward example. We can solve this easily using the addition method, which would simplify to 3x = 6 , which would further simplify to x = 2 . Using this result, we can solve for y : (2) - y  = 1  à  2 - 1 = y  à  y = 1 . Or 2(2) + y = 5  à ...
