Unformatted text preview: Growth Authors: Bill Davis, Horacio Porta and Jerry Uhl ©1996-2007 Publisher: Math Everywhere, Inc. Version 6.0 1.01 Growth LITERACY · L.1) A function f @ x D starts out at x = with a value of f @ D = 1 and goes up at constant rate of 3 units on the y- axis for each unit on the x- axis . Give a formula for f @ x D and sketch its plot on the axes below: The point plotted below is on the plot of f @ x D because f @ D = 1.- 1.0- 0.5 0.5 1.0 x- 2 2 4 6 f @ x D · L.2) A function f @ x D starts out at x = 2 with a value of f @ 2 D = 6 and goes up at a rate of - 1.5 units on the y- axis for each unit on the x- axis . Give a formula for f @ x D and sketch its plot on the axes below: The point plotted below is on the plot of f @ x D because f @ 2 D = 6. 1 2 3 4 x- 2 2 4 6 f @ x D · L.3) Given a constant b , what happens to f @ x D = 3 x + b every time x goes up by one unit? What is the growth rate of f @ x D ? Given a constant c , what happens to g @ x D = - 2 x + c every time x goes up by one unit? What is the growth rate of g @ x D ? · L.4) Linear growth is characterized by having a constant growth rate. Give a real-world example of a situation modeled by linear growth. · L.5) Most human bodies eliminate alcohol at the rate of 12 grams per hour. The typical 12- ounce American beer contains about 13.5 grams of alcohol....
