Reflection over x -2
Web20. Another way. To reflect along a line that forms an angle θ with the horizontal axis is equivalent to: rotate an angle − θ (to make the line horizontal) invert the y coordinate. rotate θ back. Further, y = m x implies tan θ = m, and 1 + m 2 = 1 cos 2 θ . Then, assumming you know about rotation matrices, you can write. WebA point and its reflection over the line x=-1 have two properties: their y-coordinates are equal, and the average of their x-coordinates is -1 (so the sum of their x-coordinates is …

Webf (-x) = Reflection across y-axis These are essential to know. Since -f (x) is a reflection across axis, we do as such: -f (x) = -1 (-4 (x+7)²-7) -f (x) = 4 (x+7)²+7 <-- you're new equation ( 6 votes) Fred Haynes 3 years ago Why does f (x) = the square root of x make the type of graph it does? • ( 3 votes) kubleeka 3 years ago Web8. máj 2013 · A reflection in the line x=2 followed by a reflection in the x axis. The point (x, y) is distance x- 2 from the line x= 2. It will be mapped to the point that distance on the other side: 2- (x- 2)= 4- x. Reflecting (x, y) in the line x= 2 maps it to (4- x, y). Reflecting in the x-axis just changes the sign on y.
