Consider the relationship between y = f(x) and y = - f(x).

What is this type of function transformation called? What does it look like on a graph?

Answer both questions in one SHORT sentence each.

The transformation from y = f(x) to y = -f(x) is called a reflection across the x-axis. On a graph, this transformation results in a mirror image of the original function flipped upside down.
