EXPONENTIAL FUNCTIONS (1.2) NAME________________________________ 1. Determine which table illustrates an exponential function and which one illustrates a linear function. Find formulas for these two functions, then find a formula for the third function. x () hx -3 1.3310 -1 1.9167 1 2.7600 3 3.9744 5 5.7231 x x () fx -2 -25.22 0 3.50 2 32.22 4 60.94 6 89.66 () gx 0.5 -1 1 0 2 1 4 2 8 3 2. Determine which situation is linear and which is exponential. Find a formula for each. A. A computer purchased for $3200 loses roughly 20% of its value each year. B. A kitchen appliance purchased for $120 loses roughly $18 in value every two years.

It is predicted that the population of a particular state will double by the year 2026. Determine the annual, monthly, and continuous growth rates. 5. The number of people who hear a rumor tends to follow a saturated growth model. Suppose a particular town has 2000 people. Three days after a rumor is introduced, 140 people will have heard it. Determine when 40% of the population will have heard the rumor....
