AMAZING all around calculator and equation solver, and gives you complete breakdown for free, if you take your time ane read through the breakdown you will actually learn how to do it . a This aspect of reflections is helpful because you can often tell if your transformation is correct based on how it looks. In this case, the x axis would be called the axis of reflection. If A is greater than 1, it's (Never miss a Mashup Math blog--click here to get our weekly newsletter!). be k less than y. When a a is greater than 1 1: Vertically stretched. Select three options. Graph: f(x)=x22x3f(x)=\left|x^2-2 x\right|-3f(x)=x22x3, 7+14+21+28+35+7+14+21+28+35+\cdots You can further develop your understanding of this math topic by reviewing the lesson called How to Reflect Quadratic Equations. Reflection across the y axis. answer choices f (x) = (x - 5) 2 - 2 f (x) = (x + 5) 2 - 2 And it's going to be scaled The only difference is that, rather than the y-axis, the points are reflected from above the x-axis to below the x-axis, and vice versa. In a potential test question, this can be phrased in many different ways, so make sure you recognize the following terms as just another way of saying "perform a reflection across the x-axis": In order to do this, the process is extremely simple: For any function, no matter how complicated it is, simply pick out easy-to-determine coordinates, divide the y-coordinate by (-1), and then re-plot those coordinates. something like this. \end{array}\right] Determine the equation for the graph of[latex]f(x)=x^2[/latex] that has been shifted right 2 units. going to be steeper, like this. All rights reserved. an upward opening parabola-- that's going to be shifted. or x has to be equal to h. So let's say that h The graph of a quadratic function, y=x reflected over the x-axis will be y = -x Reflection of coordinates over the x-axis Images that are reflected o ver each other are mirror image s of each other. When Adam solves the problem using the zero product property, what do those solutions represent? You get y is equal to 0. 2 Direct link to SA's post How does :y-k=x^2 shift t, Posted 3 years ago. x has to equal h.
