Figure 8.14. 2 The preimage above has been reflected across the y -axis. This means, all of the x-coordinates have been multiplied by -1. You can describe the reflection in words, or with the following notation: r y − a x i s ( x, y) → ( − x, y)

WebDefinition: Reflection in the 𝑥-Axis A reflection in the 𝑥 - a x i s maps 𝑃 ( 𝑥, 𝑦) → 𝑃 ′ ( 𝑥, − 𝑦). In other words, a reflection in the 𝑥 - a x i s maps point 𝑃 onto its image point 𝑃 ′ by keeping the 𝑥 -coordinate the same and changing the sign of the 𝑦 -coordinate.

WebReflections in the x-axis If \ (f (x) = x^2\), then \ (-f (x) = - (x^2)\). This means that each of the \ (y\) coordinates will have a sign change. So \ (y = 4\) would become \ (y =... WebReflect the shape in the x-axis. First go over the x – axis with a different colour so you know exactly where the mirror line is. Corner A is 4 squares to the x-axis, so corner A on the reflected shape will be 4 squares away from the x-axis. hr block free tax refund calculator
