Answer:
1. . Exponential decay function.
2. . Exponential growth function.
3. . Exponential growth function.
4. . Exponential growth function.
5. . Exponential growth function.
6. . Exponential decay function.
7. g(x) = 0.3(x). Not an exponential function.
Step-by-step explanation:
1. . This is an exponential decay function.
As the value of t increases H-value decreases.
2. . This is an exponential function of growth.
As the value of t increases y-value also increases.
3. . This is an another example of exponential growth function.
As the value of t increases f(t)-value also increases.
4. . This is again an example of exponential growth function.
As the value of t increases A-value also increases.
5. . This is again an example of exponential growth function.
As the value of t increases A-value also increases.
6. . This is another an example of exponential decay function.
As the value of t increases, H-value decreases.
7. g(x) = 0.3(x). This is a non-exponential function. (Answer)
<u>Solution-</u>
Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)
1 UK gallon = 4.5459631 lit
1 US gallon = 3.7853060 lit
As the fuel consumption rate = 40 miles per gallon
⇒ You need 1 UK gallon of fuel to go 40 miles
⇒ You need 1.2009499 US gallon of fuel to go 40 miles
Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel
⇒ To go 1 mile you will need
⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel
∴ 22.1574906 gallon of fuel is actually required.
∴ But, what she thinks will require is (As she calculated using UK gallons)
