John had $30,000 to invest. He invested part of this money in bonds paying 12% annual simple interest and the rest of the money in a savings account giving 4% annual interest. At the end of the year, he received $2,400 as extra income. How much money did John place in each investment? Bonds = x Savings = 30,000 – x .12x + .04 (30,000 – x) = 2,400 .12x + 1,200 - .04x = 2,400 .08x + 1,200 = 2,400 -1,200 -1,200 .08x = 1,200 ----------------- .08 X = $15,000 (amount put into bonds) 30,000 – 15,000 = $15,000 (amount put into savings) John put $15,000 into bonds and $15,000 into savings. 4.

...School of Information Technology 1. (25 points) The media access control (MAC) address of a network interface is a unique address. Each network interface relating to its MAC fits the criteria of a function because each device has its own, unique MAC address. Describe an everyday situation in your field that is a function. Be sure to explain exactly why the situation is a function. Using a mac address is a direct link from one connection to another, for example going from a PC to a switch, this is an example of a function because one port on the switch only goes directly to one pc each match up. 2. (20 points) Describe a chart or graph you might find related to a computer that fits the criteria for the graph of a function. Make sure to explain in detail why the graph fits the criteria. The graph of g is the graph of f shifted vertically up by 4 units, the functions meet the criterial of graph in the sense that if a vertical line is drawn it will only cut the graph once. 4. (15 points) For any given graph of a function, explain how to find its domain. If a function f does not model data or verbal conditions, its domain is the largest set of real numbers for which the value of is a real number. Exclude from a function’s domain real numbers that cause division by zero and real numbers that result in a square root of a negative number. For example = x2 – 7x contain no division nor square root. Expression x2-7x represents a real number...
