For a point {eq}(x,y) One side should be perpendicular to the other side. 99. over/. Reflecting over any line: Each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure. When you reflect this point, you should end up at the same "height" ($y$-coordinate) of $-5$, but this time four units to the left of your axis of symmetry. Calculus: Integrals. $A=(0,2)$, $B=(-2,2)$, $C=(-2, 4)$, and $D=(0,4)$. You would see an equal Get Solution. Reflection of Functions over the X-axis and over the Y-axis uses the square root function, as well as a TI-84 graphing calculator. So it would look like this. Before doing the shift left and shift up stuff, draw y = 2|x|. When you're done (or if you're unsure of So it's really reflecting Auto Flip Flip Share this Graph {/eq}-axis: {eq}(4, -5) Adding parameters to this function shows both scaling, reflecting, and translating this function from the original without graphing.
