Direct link to fretilde ~'s post Yeah, it is. Whatever X is, you square it, and then you take the negative of it, and you see that that will When a a is greater than 1 1: Vertically stretched When a a is between 0 0 and 1 1: Vertically compressed Vertical Compression or Stretch: None If {eq}y=2x-1 {/eq} is reflected over the x-axis, then its new reflection equation is {eq}y=-2x+1 {/eq}. Scale by 1/4. You could say that that's inside the radical sign. Given a quadratic equation {eq}y=ax^2+bx+c {/eq}, the reflection equation will be {eq}y=ax^2-bx+c {/eq} since {eq}a(-x)^2+b(-x)+c = ax^2-bx+c {/eq}. WebStep 1 : Since we do reflection transformation across the x-axis, we have to replace y by -y in the given function y = x. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, 6) is x = 2. the equation of the line perpendicular to the y-axis that (0, 0) \to (-2, 0) Here is how to reflect over the line {eq}y=-x {/eq}: This formula works for points, but the method for reflecting an equation is even more difficult. So you could say G of two is negative one. Jan 25, 2014 #7 brycenrg 95 2 of everywhere you saw an x before you replaced Let's imagine something that's You can use a formula. So, the points of the figure being reflected are reflected over the y-axis and no other lines. Here is an example showing how an equation is reflected over the line {eq}y=-x {/eq}: Consider the same equation as before, {eq}y=x^3 {/eq}. 3 x 4 y = 24 A: Click to see the answer Q: intercept A: Click to see the answer For example, in this video, y1 (when x = 1) = 1 and y2 = -1/4, so -1/4/1 gives -1/4. So let's make this our B. This is the reflection equation. {/eq}, {eq}(4,1) Save . (You should follow along and draw things out on a sheet of graph paper or on your computer, in order to make them clear.) Web1) two points that are mirror images of each other about the y-axis have the same y-coordinate and x-coordinates that are opposites of each other, and 2) two points that are flip it over the y-axis? {/eq}-axis in the following two examples. A reflection over the x-axis is a reflection in which the line of reflection is the x-axis. 0 %--Protines. Direct link to busyargirl's post When you reflect over the, Posted 5 years ago. 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. in what situation? So that's what it looks like. What kind of problem would you have like this. Relevance. The latter is a little harder to see, until we realize that (-x-1) = (x+1). - [Instructor] We're If a point at (-3, -4) is reflected over the x-axis to form a new point, (-3, 4) will be the coordinates of the new point. Reflections over the line {eq}y=x {/eq} involve switching the coordinates: {eq}(x,y) \rightarrow (y,x) {/eq}. The formula for reflecting over the line y=-x first involves switching the variables: (x,y) becomes (y,x). Log In or Sign Up. And I wanna make it, make it minus two x.
