To reflect a function across the x-axis (flip it upside down), you would multiply the entire function by -1. Therefore, the correct answer is:
**B. Multiply by a negative leading coefficient**
When you take a function \( f(x) \) and create a new function \( -f(x) \), it reflects the original function across the x-axis.
**B. Multiply by a negative leading coefficient**
When you take a function \( f(x) \) and create a new function \( -f(x) \), it reflects the original function across the x-axis.
