An airline operates in only 10 destinations in 2018, but plans on adding more destinations each year. in 2019, the number of destinations will be twice the initial number of destinations. then, in 2020, the number of destinations will be twice the number of destinations the previous year.
if this pattern continues, which graph represents the number of destinations in which the airline will operate over time?

The graph in the attached figure

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

where

y ----> is the number of destinations

x ----> is the number of years since 2018

a is the initial value (a=10 destinations)

b is the base

r=100%=1

b=1+r=1+1=2

The equation is equal to

using a graphing tool

Step-by-step explanation:

hello :

you add  11² to complete the square

x²+22x+11²=50+11²

(x+11)² = 171
