How does the graph of $$ f(x)=\sqrt[3]{x} $$ change when $$ f(x) $$ is replaced by $$ -7 f(x) $$ (1 point) The graph is reflected across the $$ x $$-axis and has been stretched horizontally. The graph is reflected across the $$ y $$-axis and has been compressed vertically. The graph is reflected across the $$ x $$-axis and has been stretched vertically. The graph is reflected across the $$ y $$-axis and has been compressed horizontally.

When you replace $$ f(x) = \sqrt[3]{x} $$ with $$ -7f(x) = -7\sqrt[3]{x} $$:

1. **Reflection across the $$ x $$-axis**: The negative sign (-7) reflects the graph across the $$ x $$-axis.
2. **Vertical Stretch**: The factor of 7 stretches the graph vertically by a factor of 7.

So, the correct transformation is:

**The graph is reflected across the $$ x $$-axis and has been stretched vertically.**

**Answer:**  
The graph is reflected across the $$ x $$-axis and has been stretched vertically.
The graph is reflected across the $$ x $$-axis and stretched vertically.
