If function P(integer x) returns integer y where y = 2 * x, what does P(5) evaluate to?

The function P is defined such that it takes an integer input ( x ) and returns an output ( y ), which is calculated as ( y = 2 * x ). In this case, when we provide the input ( 5 ) to the function (i.e., ( P(5) )), we will substitute ( x ) with ( 5 ).

Calculating the output:

[

y = 2 * 5

]

[

y = 10

]

Thus, ( P(5) ) evaluates to ( 10 ). Therefore, the correct answer reflects the proper application of the function by doubling the input number, which leads to the final result of ( 10 ). This confirms that the choice indicating ( 10 ) as the outcome of the function when ( 5 ) is passed as an argument is indeed accurate.
