The mapping diagram shows a functional relationship.

A mapping diagram shows a relation, using arrows, between domain and range for the following ordered pairs: (8, 4), (negative two-thirds, 3), (11, negative 1), (4, one-half).

Complete the statements.

f(4) is
.

f(x) = 4 when x is

1 answer

Sure, let's complete the statements using the given ordered pairs: (8, 4), (-2/3, 3), (11, -1), (4, 1/2).

1. **f(4) is**:

Looking at the ordered pairs, when \( x = 4 \), the corresponding \( y \)-value is 1/2.

Therefore: \[\boxed{\frac{1}{2}}\]

2. **f(x) = 4 when x is**:

Looking at the ordered pairs and searching for when \( y = 4 \), we find \( x = 8 \).

Therefore: \[\boxed{8}\]

So the complete statements are:

- \( f(4) \) is \( \frac{1}{2} \).
- \( f(x) = 4 \) when \( x \) is \( 8 \).
