For question 1-3, consider the following program: def tryIt(a ,b = 7) return a + b

#MAIN
n = int(input(‘Enter a number ‘))
Ans = tryIt(n) * 2
Print (ans)

1. What is output of the user enters 2?

2. What is output if the user enters -5?

3. What is output if the user enters 7?

1)18

2)4

3)28

Explanation:

1) ans= tryIt(2) *2

        = (2+7)* 2 =18

2) ans= tryIt(-5) *2

        = (-5+7)* 2 =4

3) ans= tryIt(7) *2

        = (7+7)* 2 =28

Functions are collections of code statements that are executed when called

The given function initializes variable b to 7, and returns the sum of b (i.e. 7) and the value passed to the function.

However; in the main function, the sum is doubled before printed.

So, the computations are as follows:

Hence, the outputs for 1 - 3 are 18, 4 and 28, respectively
