WebStart with the mirror line X horizontal, that is, its angle x = 0. The it's clear that the vector angle, z, of the reflected light is the negative of the vector angle, y, of the light itself: z = -y. Now rotate line X by d degrees around the point of reflection, either way, leaving the original light ray (angle y) fixed and letting the ... WebJan 11, 2016 · The distance between the vertex's x-coordinate and the x-coordinate of the y-intercept is the same distance between the vertex's x-coordinate and the desired point's x-coordinate. This is because the vertex acts as an axis of symmetry. The vertex of the parabola is (-7, -2). The y-intercept is (0, 145). WebWhen we multiply the parent function f (x) = bx f ( x) = b x by –1, we get a reflection about the x -axis. When we multiply the input by –1, we get a reflection about the y -axis. For example, if we begin by graphing the parent function f (x) = 2x f ( x) = 2 x, we can then graph the two reflections alongside it. simplicity\\u0027s tw
