1. Problem Description

We are given three tables of values for three functions, f(x)f(x), g(x)g(x), and h(x)h(x). We need to determine whether each table represents a function.

2. Solution Steps

A relation is a function if each input (xx-value) corresponds to exactly one output (yy-value). In other words, there should be no repeated xx-values with different yy-values.
For f(x)f(x):
The xx-values are 1, 2, 3, 4, 5, 6, and the yy-values are 72, 50, 32, 18, 8,

2. All the $x$-values are distinct, so this table represents a function.

For g(x)g(x):
The xx-values are 1, 2, 3, 4, 5, 6, and the yy-values are 128, 150, 168, 182, 192,

8. All the $x$-values are distinct, so this table represents a function.

For h(x)h(x):
The xx-values are 1, 2, 3, 4, 5, 6, and the yy-values are 2, 8, 18, 32, 50,

2. All the $x$-values are distinct, so this table represents a function.

3. Final Answer

f(x)f(x) is a function.
g(x)g(x) is a function.
h(x)h(x) is a function.
