WebWhen the figure is folded and its two parts are identical (or reflection of each other), then we can say that it has a line symmetry. How to Find Line of Symmetry of a Parabola? For a parabola with quadratic equation y = ax 2 + bx + c, line of symmetry is x = -b/2a. Why Does Parallelogram have No Line of Symmetry? WebSo use a method for computing the inverse of a function to find the reflection about the line y = x. Replace x with 6 − x. This works because if x = 3 + t, then 6 − x = 3 − t. Or, in words: if x is t units to the right from 3, then 6 − x is t units to the left from 3. black phenolic sheetWebToday, we use matrix transformations to derive a formula which we can use to reflect any point on a plane in the any linear line of the form y=ax+b (or y=mx+c).

"WebWhat it was trying to say was that you could take your function, draw the line y = x (which is the diagonal line from the bottom-left to the top-right), put a two-sided mirror on this line, and you could "see" the inverse reflected in the mirror. Practically speaking, this "reflection" property can help you draw the inverse: " - Reflection over a diagonal line formula
