Reflection on the y axis formula
WebSo, image equation of the given equation is 2x+3y = -8. Example 3 : Find the image equation of. y = 2x 2. under y = x. Solution : Required transformation : Reflection under y = x, so change x as y and y as x. Put x = -y and y = x. Original … WebAnd every point below the x-axis gets reflected above the x-axis. Only the roots, −1 and 3, are invariant. Again, Fig. 1 is y = f(x). Its reflection about the x-axis is y = −f(x). Every y-value is the negative of the original f(x). Fig. 3 is the reflection of Fig. 1 about the y-axis. Every point that was to the right of the origin gets ...
