A. f(x) = -3(1/5)^x-1
B. f(x) = -3(1/5)^x-1
C. f(x) = -1/5(3)^x-1
D. f(x) = -1/5(-3)^x-1

Respuesta :

apologiabiology
each term is multiplied by -1/5
first term is -3

an=a1(r)^(n-1)
for a1=first term
r=common ratio
n=which term


in this case
first term=-3
common ratio is -1/5
so

[tex]f(x)=-3( \frac{-1}{5})^{x-1} [/tex]

none of them
oh, A and B are the same
the one that has the -1/5 inside is the one

The one that has the -1/5 inside is the one.

each term is multiplied by -1/5.

The first term is -3

What is the formula for the sequence?

[tex]a_n=a_1(r)^{(n-1)}[/tex]

for a_1=first term

r=common ratio

n=which term

In this case

The first term=-3

The common ratio is -1/5

so, [tex]f(x)=-3(\frac{-1}{5} )^{(x-1)}[/tex]

None of them A and B are the same

The one that has the -1/5 inside is the one.
