Option 1: At x = 0,

f (x) = 128 (0.5) ^0 = 128 (1) = 128 (not satisfy the ordered pair which is (0,128))

Option 2: At x = 1,

f (x) = 128 (0.5) ^1 = 128 (0.5) = 256 (not satisfy the ordered pair which is (1,256))

Option 3: At x = 3,

f (x) = 128 (0.5) ^3 = 128 (1/2) ^3 = 128 (1/8) = 16 (satisfy)

Hence, the answer is Option 3.
