This mapping shows a functional relationship.

Question

A mapping diagram shows a relation, using arrows, between domain and range for the following ordered pairs: (2, 4), (negative 3, 0), (negative 1, negative 1), (4, 3).

When f(x)=4, what is the value of x?

0
2
3
4

Answer 1

To find the value of \( x \) such that \( f(x) = 4 \), we need to look at the ordered pairs provided in the mapping diagram:

• (2, 4)
• (-3, 0)
• (-1, -1)
• (4, 3)

From the ordered pairs, we can see that \( f(2) = 4 \). This means when \( f(x) = 4 \), the corresponding value for \( x \) is 2.

Therefore, when \( f(x) = 4 \), the value of \( x \) is \( \boxed{2} \).
