Ageometric sequence has an initial value of 1/2 and a common ratio of 8. write an exponential function to represent this sequence. a: f(x) = 8· (1/2)^x b: f(x) = 8· (1/2)^-1 c: f(x) = 1/2 ·8^x d: f(x) = 1/2 ·8^x-1 me

D

Step-by-step explanation:

the n th term of a geometric sequence is

= a

Where a is the first term and r the common ratio

here a = and r = 8, hence

f(x) = → D

The correct option is  D.

Step-by-step explanation:

It is given that the initial value of a GP is 1/2 and common ratio is 8. It means

The nth term of a GP is

where, is inital value and r is common ratio.

Substitute and in the above formula.

The exponential function to represent this sequence is

Therefore the correct option is D.
