Question

How do you reflect a function across the x-axis (flip it upside down)? (1 point)

Change the variable

Use an irrational exponent

Subtract a number larger than 10

Multiply by a negative leading coefficient

Answer 1

To reflect a function across the x-axis (flip it upside down), you would **multiply the entire function by -1**. This means if you have a function \( f(x) \), reflecting it across the x-axis would result in \( -f(x) \).

Among the options provided, the correct answer is:

**Multiply by a negative leading coefficient.**
