which ordered pairs lie on the graph of the exponential function f(x)=128(0.5)^x. choose all the correct answers
(0,1)
(1,64)
(3,16)
(8,0.5)

To determine the correct ordered pairs which will agree with the function, we can substitute values to the function and see whether it agree with each other. We do as follows:

(0,1)
 f(x)=128(0.5)^0
 f(x)=128

(1,64)
 f(x)=128(0.5)^1
f(x) = 64  <CORRECT ANSWER

(3,16)
 f(x)=128(0.5)^3
f(x) = 16 <CORRECT ANSWER

(8,0.5)
 f(x)=128(0.5)^8
f(x) = 1/2

Hope this answers the question. Have a nice day.

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
