Answer: A. 
Step-by-step explanation:
Total digits on keypad = 5
According to permutation,
If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!
= 5 x 4 x 3 x 2 x 1 [n!=n x (n-1) x (n-2)x ... x 1]
=120
The probability that someone guesses the correct code = 

Hence, the correct option is A.
Given:
The function is:

To find:
The initial value of the function.
Solution:
We have,

The value of the function at x=0 is called the initial value of the function.
For x=0, we get


Clearly 0.88 is a non zero number and zero to the power of a non zero number is always 1.


Therefore, the initial value of the function is 350.
