How to work out equations of reflected graphs
WebIn standard reflections, we reflect over a line, like the y-axis or the x-axis. For a point reflection, we actually reflect over a specific point, usually that point is the origin . Formula r ( o r i g i n) ( a, b) → ( − a, − b) Example 1 r o r i g i n ( 1, 2) = ( − 1, − 2) Example 2 r o r i g i n ( 3, 4) = ( − 3, − 4) WebThey are symmetric about the origin. The equation of graph 𝐴 is 𝑦 = 1 3 √ 𝑥 + 2 + 1 . Knowing that a point reflection about the origin is equivalent to a reflection in the 𝑥 -axis followed …
