To determine which family of functions the described function might belong to, let's analyze the behavior of each option as the domain approaches positive and negative infinity:

1. **Absolute Value Function**: The absolute value function, $$ f(x) = |x| $$, approaches positive infinity as $$ x $$ approaches positive infinity, but it approaches 0 as $$ x $$ approaches negative infinity. Thus, it does not fit the description.

2. **Exponential Function**: An exponential function, such as $$ f(x) = e^x $$, approaches positive infinity as $$ x $$ approaches positive infinity, but approaches 0 as $$ x $$ approaches negative infinity. This also does not fit the description.

3. **Cube Root Function**: The cube root function, $$ f(x) = \sqrt[3]{x} $$, approaches positive infinity as $$ x $$ approaches positive infinity and negative infinity as $$ x $$ approaches negative infinity. This fits the description.

4. **Square Root Function**: The square root function, $$ f(x) = \sqrt{x} $$, approaches positive infinity as $$ x $$ approaches positive infinity, but is undefined for negative values of $$ x $$. Thus, it does not fit the description.

Based on this analysis, the function described belongs to the **cube root** family.
The function belongs to the cube root family.
