Select each correct answer.



​ (0,1) ​

​ (1,64) ​

​ (3,16) ​

​​ (8,0.5) ​

Respuesta :

Applying the numeric values, it is found that these following ordered pairs lie on the graph of the function [tex]f(x) = 128(0.5)^x[/tex]:

(1,64), (3,16) and (8,0.5).

Verifying if point (0,1) lies on the graph:

[tex]f(0) = 128(0.5)^0 = 128(1) = 128[/tex]

Since [tex]f(0) \neq 1[/tex], point (0,1) does not lie on the graph of the function.

Now, for point (1,64):

[tex]f(1) = 128(0.5)^1 = 64[/tex]

Since [tex]f(1) = 64[/tex], point (1,64) lies on the graph of the function.

For point (3,16):

[tex]f(3) = 128(0.5)^3 = \frac{128}{8} = 16[/tex]

Since [tex]f(3) = 16[/tex], point (3,16) lies on the graph of the function.

Finally, for point (8,0.5):

[tex]f(8) = 128(0.5)^8 = \frac{128}{256} = 0.5[/tex]

Since [tex]f(8) = 256[/tex], point (8,0.5) lies on the graph of the function.
