Which formula can be used to describe the sequence?

mafiozo [28]

Answer:

The formula that can be used to describe the given sequence is $f(x)=-4(6)^{x-1}$

Step-by-step explanation:

Given : sequence -4, −24, −144,...

We have to find the formula that can be used to describe the given sequence -4, −24, −144,...

A geometric sequence is a sequence in which each higher term is multiplied by a constant number called common ratio.

Written as a, ar , ar², ar³., ....

and general term is calculated as $a_n=ar^{n-1}$

Where a is first term and r is common ratio.

Consider the given sequence -4, −24, −144,...

We find the common ratio ,

$a=-4, \\\\ar=-24,\\\\\ ar^2=-144$

Thus, common ratio is given as $r=\frac{ar}{r}=\frac{-24}{-4}=6$

Thus, the given sequence is a geometric sequence.

The general term is given by $a_n=ar^{n-1}$

Put a = -4 , r = 6

We have

$a_n=-4(6)^{n-1}$

Thus, the formula that can be used to describe the given sequence is $f(x)=-4(6)^{x-1}$

Use a table of function values to approximate an x-value in which the exponential function exceeds the polynomial function. In y

BabaBlast [244]

F(x)=2ˣ
f(x)
(x,y)
(0,1)
(1,2)
(2,4)
(3,8)
(4,16)
(5,32)
(6,64)
(7,128)
(8,256)
(9,512)
(10,1024)

h(x)
(x,y)
(0,8)
(1,10)
(2,18)
(3,38)
(4,76)
(5,138)
(6,230)
(7,358)
(8,528)
(9,736)
(10,1018)

so somwehre between x=9 and x=10

hmm
f(9.5)=724.007
h(9.5)=874.875

go to 9.75
f(9.75)=944.609
h(9.75)=861.078

up

9.9
f(9.9)=955.426
h(9.9)=988.199
up

9.95
f(9.95)=989.119
h(9.95)=1003.02
up

9.99
f(9.99)=1016.93
h(9.99)=1014.99

a bit down
9.98
f(9.98)=1009.9
h(9.98)=1011.99

a bit up
9.985
f(9.985)=1013.41
h(9.985)=1013.49
pretty close, ya

so about at 9.985=x
if we graphed, we get that x=9.98512070914982..., so we are pretty close
