The value of the car after three years is £6936
<h3>How to determine the value of the car?</h3>
The initial value of the car is given as:
Value = £12000
When the value depreciates by 20% after the first year, the new value of the car is:
New = £12000 * (1 - 20%)
Evaluate
New = £9600
When the value depreciates by 15% after the second year, the new value of the car is:
New = £9600* (1 - 15%)
Evaluate
New = £8160
When the value depreciates by 15% after the third year, the new value of the car is:
New = £8160 * (1 - 15%)
Evaluate
New = £6936
Hence, the value of the car after three years is £6936

Answer:
see explanation
Step-by-step explanation:
The translation represented by
interprets as a shift of 1 unit to the right ( add 1 to x- coordinate ) and a
shift of 4 units down ( subtract 4 from the y- coordinate ), then
(1, 4 ) → (1 + 1, 4 - 4 ) → (2, 0 )
(4, 4 ) → (4 + 1, 4 - 4 ) → (5, 0 )
(6, 2 ) → (6 + 1, 2 - 4 ) → (7, - 2 )
(1, 2 ) → (1 + 1, 2 - 4 ) → (2, - 2 )

Step-by-step explanation:
Inverse function defined as the the function that undergoes the action of the other function.
A function is the inverse of f if whenever y =f(x) and
To find the inverse of the function:
Q1.
Given the function: f(x) = 7x -1
Put y for f(x) and solve for x;
y= 7x -1
Add 1 both sides we get;
y + 1 = 7x
Divide both sides by 7 we get;
Put for x;
Interchange y =x, we have
Q 2.
Given the function:
Put y for f(x) and solve for x;
Add 7 both sides we get;
taking cube root both sides we get
Put for x;
Interchange y =x, we have
Q3 .
Given the function:
Put y for f(x) and solve for x;
Add 3 both sides we get;
Divide both sides by 5 we get;
taking cube root both sides we get
Put for x;
Interchange y =x, we have
