A) It can be represented using the formula f(x + 1) = 6/5(f(x)) when f(1)=10/3
B) It can be represented using the formula f(x)=4[6/5]x
C) It can be represented using the formula f(x)= 10/3 [6/5]x-1
D) The domain of the sequence is all real numbers.
E) The range of the sequence is all natural numbers.
OpenStudy (anonymous):
it is a geometric sequence
find r
try to find tn where n=x
OpenStudy (anonymous):

How B,C,E? show
OpenStudy (anonymous):
because it says to [ check all that apply]
OpenStudy (anonymous):
In C\[f(x)=\frac{ 10 }{ 3 }\left( \frac{ 6 }{ 5 } \right)^{x-1}\]
but it is not exponential in your statement.
OpenStudy (anonymous):
kk
OpenStudy (anonymous):
if it is like this then it is also true

in E 10/3,24/5,144/25 are not natural numbers.
OpenStudy (anonymous):
that will be real number then because those numbers are real
