QUESTION 7:

Suppose function f is defined with the signature: f(n), where n is a float value. In the function, there is a statement that modifies n. Which of the following statements are true?

1. f(3) is a valid function call

2. After the function call f(n) where n=4, value of n will reflect the modified value in the function

3. After the function call f(n) where n=3.5, this value of n remains the same

4. x = f(3.0) is a valid function call
