What is a difference between functions that return values and functions that don't return values?
1 pt

Functions that return values can have input as paramaters

Functions that return values have to be called whereas functions that do not don't have to be called

Functions that return values have results that can be saved to variables whereas functions that do not return values don't have results that can be saved to variables

Functions that return values don't have output and functions that don't return values do.

Answer 1

Let's address each question one by one:

### Question 1:
**How many total lines of output will show up if you run the code below?**
```python
def add(x, y):
print(x + y)

def multiply(x, y):
return x * y

add(1, 2)
multiply(2, 3)
print(multiply(3, 4))
```

1. `add(1, 2)` will print `3`. This contributes **1 line** of output.
2. `multiply(2, 3)` returns `6`, but it is not printed, so it contributes **0 lines**.
3. `print(multiply(3, 4))` calls `multiply` which returns `12`, and this value is printed. This contributes **1 line** of output.

**Total lines of output**: 1 (from `add`) + 0 (from unused return) + 1 (from `print`) = **2** lines.

**Answer:** **2**


### Question 2:
**What is the output of this code?**
```python
def add(x, y):
return x + y

def multiply(x, y):
return x * y

print(add(1, 2))
multiply(2, 3)
print(multiply(3, 4))
```

1. `print(add(1, 2))` will output `3`.
2. `multiply(2, 3)` returns `6`, but it is not printed (thus does not contribute to the output).
3. `print(multiply(3, 4))` calls the `multiply` function and prints `12`.

So the printed output will be:
- First line: `3`
- Second line: `12`

**Complete output:**
```
3
12
```

**Answer:** **3, 12**


### Question 3:
**What is the difference between functions that return values and functions that don't return values?**

- Functions that return values have results that can be saved to variables whereas functions that do not return values don't have results that can be saved to variables.

This statement correctly describes the fundamental difference in how you can use the outputs of these functions.

**Answer:** **Functions that return values have results that can be saved to variables whereas functions that do not return values don't have results that can be saved to variables.**
