According to NASDAQ: WEN they are the world’s third largest quick service hamburger company. To us this is known as a fast food restaurant. Wendy’s has more than 6,500 restaurants in the United States and 27 other United States territories in the world. When Dave Thomas opened the first Wendy’s restaurant in Ohio in 1969 he vowed to have quality food. That is why today, that they still serve the best quality foods around that is made to order.

Composition and Inverse Functions MAT 222: Intermediate Algebra Instructor October 12, 2014 Composition and Inverse Functions Functions are helpful in algebra to determine model dependencies among different variables. For example, some situations require many levels of dependencies and are useful to express the final variable in terms of the first variable. Function composition defines a variable in terms of another one while reducing the level of dependencies; and an inverse function comes into play when checking a correlation between dependent and independent variables. This paper will outline and solve a true composition and inverse function. The functions are: fx=2x+5 gx=x2-3 hx=7-x3

3. Discuss what it’s used for (3 applications used in algebra) & name and explain three patterns (1 algebraic) Pascal’s Triangle has various uses within algebra. For example, Pascal’s Triangle can be used to find out how many combinations of the two faces of a coin will result from x number of tosses. The number of tosses tells you which row to look at in the
e) Set the left side of the equation equal to the positive square root of the number on the right side and solve for x. f) Set the left side of the equation equal to the negative square root of the number on the right side of the equation and solve for x. A) x² - 2x – 13 = 0 x² - 2x = 13 4x² - 8x = 52 4x² - 8x + 4 = 56 (2x – 2) ± 56 2x – 2 = 56 2x – 2 = 56 2x = 56+2 2x = 56+2 x = 56+2/2 x = 56+2/2 Project 2 C) x² + 12x – 64 = 0 -x² + 12x = 64 4x² + 48x = 256 4x² + 48 + 144 = 400 2x + 12 = ±20 2x +12 = 20 2x + 12 = -20 2x = 8 2x = -32 x = 4 x = -16 The method selected was the method shown in our text. I do not think I will ever have a chance to use this knowledge in a real-world situation. Algebra and Geometry are the hardest subjects for me, and I do not retain the teaching very well, so I am sure I will never use this formula. References Bluman, A.
