Question

Use a table to perform the reflection of y = f(x) across the y-axis. Identify the graph of the function and its reflection

Answer 1

Last Graph is the answer if the question has y = f(x) across the x-axis

Explanation:

In a reflection across the x-axis, only the y-coordinate changes. The y-coordinate in each point in the image is the opposite of the y-coordinate in each point in the pre-image.

preimage → image

x y y → −y (x, y)

−5 3 3 → −3 (−5, −3)

−3 −1 −1 → 1 (−3, 1)

−2 1 1 → −1 (−2, −1)

Use the table to graph the function and its reflection across the x-axis.

Answer 2

The Correct choice is 1st Graph.
