Find the common ratio of the give 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

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
