81, 27, 9, find the common ratio of the given sequence, and write an exponential function which represents the sequence. use n = 1, 2, 3, a) 3; f(n) = 81^n-1 b) 3; f(n) = 81(3^)n-1 c) 1/3; f(n)=81(3)^n-1 d) 1/3; f(n)=81(1/3)^n-1

yess

step-by-step explanation:

idk whyy this is happening, i cant even read my notification bc i keep getting errors

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
