On a coordinate plane, 3 points are plotted. The points are (1, 80), (2, 20), (3, 5). Which function can be used to represent the graphed geometric sequence? f(x) = 80(One-fourth) Superscript x minus 1 f(x) = 320(One-fourth) Superscript x minus 1 f(x) = 80(4)x – 1 f(x) = 320(4)x – 1

(A)

Step-by-step explanation:

Given the three points plotted on a coordinate plane

Let us consider the values in the y-axis i.e. f(x)

80, 20, 5

We notice that each succeeding term occurs by the division of the previous term by 4.

Precisely:

This is a geometric sequence where the:

First Term =80

Common ratio =

Therefore, the function which can be used to graph the geometric sequence is:
