How to stretch a function in x-direction?Īgain, like moving, stretchig is more difficult: We have to replace every x by (Mind that it is again not the way you may think: Stretching does not mean multiplying by, but dividing byĭein Browser unterstützt den HTML-Canvas-Tag nicht. Transform the function by 2 in y-direction stretch : Reflections create mirror images of points, keeping the same distance from the line. For example, lets stretch by Factor in y-direction. We can plot points after reflecting them across a line, like the x-axis or y-axis. This is easy, again: Just multiply your whole function by the stretching factor. How to stretch a function in y-direction? | Apply the higher binomial formula with a= and b= over time and recognize you when you return to our Services.
Move the graph of by 2 in direction right : transform x, 2(3 x +1)+5 transform x, 41. Here is another example involving the latter function. In math, you can create mirror images of figures by reflecting them over a given line. But if you want to go in the opposite direction, you replace x by. When you look in the mirror, you see your reflection. Try making a visual or mental picture of these reflections. Solution for Rules for Reflections on a Coordinate Plane Reflection across the x-axis Reflection across the y-axis (x, y)(-x,y) (x, y)V, x) Reflection. and mind the sign: If you want to go in x-direction, replace x by.If you want to move in x-direction, it is more difficult for two reasons: For example, lets move this Graph by units to the top.ĭein Browser unterstützt den HTML-Canvas-Tag nicht. Just add the transformation you want to to. In general, transformations in y-direction are easier than transformations in x-direction, see below. In a reflection about the x-axis, the x-coordinates stay the same while the y-coordinates take on their opposite signs. The most common cases use the x-axis, y-axis, and the line y x as the line of reflection. This depends on the direction you want to transoform. There are a number of different types of reflections in the coordinate plane. How to transform the graph of a function?
