What is exponential function?
An exponential function is defined by the formula f(x) = [tex]a^{x}[/tex], where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
The exponential function is an important mathematical function which is of the form
f(x) = [tex]a^{x}[/tex]
Where a > 0 and a is not equal to 1.
x is any real number.
Given
Car cost when bought A = £ 6200
Value of a car decreases by 7.2% each year.
n = 1
r = 7.2% or 0.072
The car will be worth after one year
[tex]y= A (1-r)^{n}[/tex]
⇒ [tex]y =6200(1-0.072)^{1}[/tex]
⇒ [tex]y = 6200(0.928)[/tex]
⇒ y = £ 5753.6
Hence, the car will be worth after one year is £ 5753.6.
