That is: In other words, a reflection over the y- axis will be given by: To shift horzontally, we add if we are moving. To reflect a function over the y- axis, we multiply the input by a negative. Find a point on the line of reflection that creates a minimum distance. We are given the parent function: And we want to find the equation after a reflection in the y- axis followed by a translation of three units right.Determine the number of lines of symmetry.(iii) Write the co-ordinates of the point to which M is mapped on reflection in (i) X- axis, (ii) Y-axis, (iii. It is common to label each corner with letters, and to use a little dash (called a Prime) to mark each corner of the reflected image. It really does flip it left and right But you cant see it, because x 2 is symmetrical about the y-axis. Lesson Overview: In this lesson, students will observe what happens when a segment is reflected over the x-axis or the y-axis. We can flip it left-right by multiplying the x-value by 1: g(x) (x) 2. ![]() (i) Name the image of P on reflection at the origin. This is also called reflection about the x-axis (the axis where y0) We can combine a negative value with a scaling: Example: multiplying by 2 will flip it upside down AND stretch it in the y-direction.
