Bao has an original oil painting worth 30{,}00030,00030, comma, 000 Chinese Yuan. Each year the painting's value increases by 15\%15%15, percent.
Which graph best represents the relationship between time and the painting's value?

Answer 1

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$y=a(1+r)^x$

where

y is the painting's value

x is the time in years

a is the initial value

r is the rate of change

we have

$a=30,000, r=15\%=15/100=0.15$

substitute

$y=30,000(1+0.15)^x$

$y=30,000(1.15)^x$

using a graphing tool

The graph in the attached figure
