Suppose an iphone loses 63% of its value each year. write a function that represents the value of the phone after x years.

The function which represent the phone value after x years                      f = i

Step-by-step explanation:

Given as :

The rate of depreciation of i-phone value each year = r = 63%

The initial value of i-phone = $ i

The final value of i-phone = $ f

The time period for depreciation = x year

Now, According to question

The final value of i-phone = The initial value of i-phone ×

Or, $ f = $ i ×

Or, $ f = $ i ×

Or, $ f = $ i ×

So, The function which represent the phone value after x years =                    f = i

Hence, The function which represent the phone value after x years                     f = i  Answer
