A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries 12. 5, 2. 5, 0. 5, 0. 1, 0. 2. Which exponential function is represented by the table? f(x) = 0. 2(0. 5x) f(x) = 0. 5(5x) f(x) = 0. 5(0. 2x) f(x) = 0. 2(0. 2x).
