Domain:
Step-by-step explanation:
The domain of a function is all values of x such that f(x) exists.
In our case we have the following function:

We know that x and f(x) are real numbers, therefore the domain will be the interval
, or in other words, the domain is all real numbers.

The number (62/495) is a rational number because it is a ratio between 62 and 495
And, 62 ÷ 495 = 0.1252525252525252525252............
So, Its equivalent decimal notation is a repeating decimal number
Answer: 895 phones
Step-by-step explanation:
Given that :
The function : y = 1.28e^1.31x ; is used to model the number of camera phones shipped since 1997
y = number of camera phones ; x = number of years since 1997
The number of camera phones shipped in the year 2002 can be obtained thus ;
x = 2002 - 1997 = 5 years
y = 1.28e^(1.31 * 5)
y = 1.28e^6.55
y = 1.28(699.24417)
y = 895.03254
y = 895 phones
Let, the two-digit number = xy
It is given that, xy = x + y²
Then, number which obey the rule is 89.
Check: 8 + 9² = 8 + 81 = 89 [ Itself ]
In short, Your Answer would be: 89
Hope this helps!
