Look at the graph.
which function can be used to represent the graphed geometric sequence?

answer choices:

a) f(x)=80(1/4)^x-1

b) f(x)=320(1/4)^x-1

c) f(x)=80(4)^x-1

d) f(x)=320(4)x-1

Step-by-step explanation:

Fro the graph, the first three terms of the sequence are 80,20,5,...

This is a geometric sequence with first term

The common ratio is

The function is given by

We substitute the values we got from the graph into this formula to get:

The correct answer is A

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
