We are going to continue the process; this time we are going to evaluate both functions at x=2.4:
For our first function:




For our second function:




To the nearest tenth:

We can conclude that the positive solution of our functions to the nearest tenth is

.
Answer:
The graph should look something like this.
Step-by-step explanation:
Area of 3400 decreases by 7.25%.
Rewrite 7.25% as a decimal.
This leads to 0.0725.
So, (3400)(0.0725) = 246.5.
Now (246.5)(13 years) = 3,276.
The area after 13 years will be
3,276 km^2.
y=mx+b plus in slope and you get your answer
