2. Decide whether the table represents a linear or exponential function. Circle either linear or exponential. Then, write the function formula. a. 0 1 2 3 4 5 6 7 x 2 5 8 11 14 17 20 23 y Linear or exponential? = __________________. y b. 0 1 2 3 4 5 6 7 x 3 6 12 24 48 96 192 384 y Linear or exponential? = __________________. y c. 0 1 2 3 4 5 6 7 x 10 5 2.5 1.25 .625 .3125 .15625 .078125 y Linear or exponential? = __________________. y d. 0 1 2 3 4 5 6 7 x 12 8 4 0 -4 -8 -12 -16 y Linear or exponential? = __________________ y e. 0 1 2 3 4 5 6 7 x 50 35 24.5 17.15 12.005 8.4035 5.88245 4.117715 y Linear or exponential? = __________________ y f. 0 1 2 3 4 5 6 7 x 40 35 30 25 20 15 10 5 y Linear or exponential? = __________________ y g. 0 1 2 3 4 5 6 7 x .4 .6 .9 1.35 2.025 3.0375 4.55625 6.834375 y Linear or exponential? = __________________ y
