organization in order to forecast? Be sure you explain "why" you selected each variable and why it is important to forecasting.. Sales forecasts are common and essential tools used for business planning‚ marketing‚ and general management decision making. A sales forecast is a projection of the expected customer demand for products or services at a specific company‚ for a specific time horizon‚ and with certain underlying assumptions. A separate but related projection is the market forecast‚ which is an attempt

al.‚ 2012). There are two methods which are Income Smoothing and Big Bath. “Income Smoothing involves taking steps to reduce the good years and defer them for use during the business down-turn years” (Gin Chong‚ 2006). In comparison‚ Big Bath manipulation in the financial statistics indicates a great fluctuation. However‚ Income Smoothing is more ethical in accounting practice than Big Bath due to the reasons compared below. Income Smoothing has been applied in financial accounting because of

LOGARITHMIC AND EXPONENTIAL FUNCTIONS Inverse relations Exponential functions Exponential and logarithmic equations One logarithm THE LOGARITHMIC FUNCTION WITH BASE b is the function y = logb x. b is normally a number greater than 1 (although it need only be greater than 0 and not equal to 1). The function is defined for all x > 0. Here is its graph for any base b. Note the following: • For any base‚ the x-intercept is 1. Why? To see the answer‚ pass your mouse over the colored

EXPONENTIAL AND LOGARITHMIC FUNCTIONS I.EXPONENTIAL FUNCTION A. Definition An exponential function is a function defined by f(x) = ax ‚ where a > 0 and a ≠ 1. The domain of the function is the set of real numbers and the range is the set of positive numbers. B. Evaluating Exponential Functions 1. Given: f(x) = 2x‚ find a. f(3) = ____ b. f(5) = _____ c. f(-2) = ______ d. f(-4) = ______ 2. Evaluate f(x) = ( 1)x if 2 a. x = 2 ____ b. x = 4 _____ c. x = -3 ______ d

You must complete Part 1 (60 points)‚ but you may choose to do either Part 2 or Part 3 (40 points each). You may also do all three parts for a total of 140 points; however‚ you must fully complete either Part 2 or Part 3 to get credit (NOT ½ of Part 2 and ½ of Part 3). This project is due on December 5th. Turning it in late forfeits your right to extra credit and there will be
