In this lesson, understand what a symmetric graph is. Understand what is x-axis symmetry and y-axis symmetry and how a test for symmetry is done...
Symmetry is when there is a perfect replica of a line or a shape. You can visually identify symmetry graphically by folding the graph along either the x- or the y-axis. The x-axis is the horizontal line that goes across the center of the graph, so if you have a line that is ...
For the function y = x^4, its symmetry is: A. Only about the x-axis B. Only about the y-axis C. About both the x-axis and the y-axis D. About the origin 相关知识点: 试题来源: 解析 B。y = x^4 是一个偶函数,其图像关于 y 轴对称。
Does the x mean the x-axis, y mean y-axis, and C mean slope? Context is Key: In mathematics, a lot of the struggle involved in understanding problems comes from understanding the context. For example, in the explanation below, we can say tha...
Reflection in the y-axis y=f(–x) (x,y) is mapped to (–x,y) Reflection in the line y=x (x,y) is mapped to (y, x) Symmetry A line is called an axis of symmetry if it is possible to pair points of the graph in such a way that the line is the perpendicular bisector of...

Step 6.1 The focus of a parabola can be found by adding to the y-coordinate if the parabola opens up or down. Step 6.2 Substitute the known values of , , and into the formula and simplify.Step 7 Find the axis of symmetry by finding the line that passes through the vertex and the fo...
Use the algebraic tests to check for symmetry with respect to both axes and the origin. y = x^3 How to prove the linearity of a reflection system? What is A' if it is the image of A(3, 5), after a reflection in the lin...
Find the Axis of Symmetry y=x^2+2x+1 ( y=x^2+2x+1) 相关知识点: 试题来源: 解析 Rewrite the equation in vertex form. ( y=((x+1))^2+0) Use the vertex form, ( y=a((x-h))^2+k), to determine the values of ( a), ( h), and ( k). ( a=1) ( h=-1) ( k=...
