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

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

• A. 2
• B. 5
• C. 10
• D. 25

Answer: (C)

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.

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.
