4/7 = 8/14 = 12/21 = 16/28, etc
Answer is A.Rational number
The Price of Car A rounded to the Nearest £100 is £12400
The Price of Car B rounded to the Nearest £100 is £16800
The Price of Car C rounded to the Nearest £100 is £14600
Difference between the Rounded Price and Original Price of Car A :
⇒ (£12400 - £12380) = £20
Difference between the Rounded Price and Original Price of Car B :
⇒ (£16800 - £16760) = £40
Difference between the Rounded Price and Original Price of Car C :
⇒ (£14600 - £14580) = £20
From the above, We can Notice that :
The Price of Car B changes by the greatest amount.
Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
<h3>What is an exponential function?</h3>
It is modeled by:
In which:
- a is the initial value, that is, y when x = 0.
- b is the rate of change, as a decimal.
Function 1 is given by:
Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:
Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.

Answer:
6
Step-by-step explanation:
f(6) is the y-value when x = 6
From inspection of the graph, f(6) = -6
g(5) is the y-value when x = 5
From inspection of the graph, g(5) = -5
Substitute the found values into the given equation:
4 · f(6) - 6 · g(5)
= 4 · (-6) - 6 · (-5)
= -24 - (-30)
= -24 + 30
= 6
