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

(0, 1)

(1, 64)

(3, 16)

(8, 0.5)

To solve which ordered pair lie on the graph of the given function f(x) = 128(0.5^2)

You mus substitute each ordered pair then check if it satisfy the given function

(0,1)

1 = 128(0.5^0)

1 = 128 so wrong

(1, 64)

64 = 128(0.5^1)

64 = 64 correct

(3, 16)

16 = 128(0.5^3)

16 = 16 correct

0.5 = 128(0.5^8)

0.5 = 0.5 correct

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
