Answer:
1. A function can use variables as parameters.
2. A function can have more than one parameter.
3. The definition of a function must come before where the function is used.
Step-by-step explanation:
The definition of a function can come before or after it is used - I am pretty sure it cannot be placed after the function is being used. It should always come before it is used, so this statement is false.
A function can use variables as parameters - this is true, variables are just labels to hold data.
A function can have more than one parameter - this is true.
A function must have a return value - functions do not always have to return values. It could simply print, so this statement is false.
The definition of a function must come before where the function is used - As said earlier, the definition of functions must come before it is used/called. This statement is true.
Hope this helps :)
