Which ordered pairs lie on the graph of the exponential function f (x) = 128 (0.5) Choose all correct answers.

Question 1 options: (0, 1)

(1, 64)

(3, 16)

(8, 0.5)

To determine the ordered pair that lies on the graph of the exponential function f (x) = 128 (0.5^x), we can substitute each option and look at which pair agree with the function. We do as follows:

f (x) = 128 (0.5^x)

(0, 1)

f (x) = 128 (0.5^0)

f (x) = 128 <---not the answer

(1, 64)

f (x) = 128 (0.5^1)

f (x) = 64 <---the answer

(3, 16)

f (x) = 128 (0.5^16)

f (x) = 0.002 <---not the answer

(8, 0.5)

f (x) = 128 (0.5^0.5)

f (x) = 90.51 <---not the answer
