Version 6.0 1.01 Growth LITERACY Â· 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 Â· 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 Â· 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 ? Â· L.4) Linear growth is characterized by having a constant growth rate. Give a realworld example of a situation modeled by linear growth. Â· 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....
