Which is an exponential growth function?
a home’s value increases at an average rate of 5.5% each year. the current value is $120,000. what function can be used to find the value of the home after x years?
f(x) = 120,000(1.055x)
f(x) = 120,000(0.055)x
f(x) = 120,000(1.055)x
f(x) = [(120,000)(1.055)]x

Step-by-step explanation:

In this problem we have a exponential function of the form

where

f(x) a home's value

x the number of years

a is the initial value

b is the base

b=(1+r)

r is the rate of grown

we have

a=$120,000

r=5.5%=5.5/100=0.055

b=1+0.055=1.055

substitute

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
