Reflection Graph

Function Input

Enter f(x):

Use sin(x), cos(x), tan(x), exp(x), powers like x^2, 3x, etc.

Horizontal zoom

Show y = f(x)

Show y = -f(x)

What this shows

This tool graphs your function y = f(x) and its reflection y = -f(x), which flips the graph in the x‑axis.

• Positive values become negative
• Negative values become positive
• Zeros stay in the same place

Try different functions and see how the reflection behaves. Notice that the shape is the same, but every point is mirrored vertically.
