Question

Examine the following graph, where a transformation maps P(x) to I(x)

Which statement best describes the transformation?

1. It is a translation 8 units up.
2. It is a translation 8 units down.
3. It is a reflection over the x-axis.
4. It is a reflection over the y-axis.

Answer 1

The answer is 3) Reflection over the x-axis.

When the point is reflected above or below the x-axis, then it is a reflection over the x-axis. The same concept as the y-axis.

The translation is when the line in the graph moves upward/downward.

Answer 2

The correct answer is 3.
