### Question 6

Which of the following is a definition of the one-to-one function?  
Select ALL that apply.

- [ ] If codomain of the function \( f \) equal to the range of \( f \).

- [ ] The function is injective and surjective at the same time.

- [ ] \( f(a) = f(b) \) implies that \( a = b \), for all \( a, b \) in the domain of \( f \).

- [ ] \( f(a) \neq f(b) \) whenever \( a \neq b \), for all \( a, b \) in the domain of \( f \).

### Question 7

Match the following properties of the function with their definitions.

- Function \( f \) is a one-to-one function  
- Function \( f \) is an onto function  
- Function \( f \) is a one-to-one correspondence  
- Function \( f \) is injective  
- Function \( f \) is surjective  

**Definitions:**

A. if and only if for every element \( b \) in the codomain there is an element \( a \) in the domain, such that \( b = f(a) \).

B. if and only if \( f(a) = f(b) \) implies that \( a = b \) for all \( a \) and \( b \) in the domain of \( f \).

C. if and only if \( f \) is one-to-one and onto at the same time.
