Reflecting triangles on a graph
Web26. aug 2016 · Firstly, note that the algorithm does not so much count the number of triangles, but rather returns whether one exists at all. For the first algorithm, the analysis becomes simple if we assume that we can do the lookup of (a, b) is an edge in constant time. (Since we loop over all vertices for all edges, and only do something with constant … WebExample 4: applying a reflection in the y- axis. The diagram shows the graph of y=f (x) y = f (x) and a point on the graph P (2,5). P (2,5). Sketch the graph and state the coordinate of the image of point P P on the graph y=f (-x). y …
Reflecting triangles on a graph
Did you know?
WebThe graph below shows triangle ABC being reflected in the line y = x. Plot the co-ordinates of the reflected triangle by left clicking your mouse on the graph shown. Rotation This needs 3 pieces of information: 1. Angle (it will probably either be 90 0 or 180 [sip]0). 2. Direction (clockwise or anti-clockwise). 3. WebExample 1. Fig. 1 is the graph of this parabola: f ( x) = x2 − 2 x − 3 = ( x + 1) ( x − 3). The roots −1, 3 are the x -intercepts. Fig. 2 is its reflection about the x-axis. Every point that was above the x -axis gets reflected to below the x -axis. And every point below the x -axis gets reflected above the x -axis.
WebA function can be reflected about an axis by multiplying by negative one. To reflect about the y-axis, multiply every x by -1 to get -x. To reflect about the x-axis, multiply f(x) by -1 to get -f(x). Putting it all together Consider the basic graph of the function: y = f(x) All of the translations can be expressed in the form: Web30. jan 2024 · If we were to approach this task again under the same conditions and time restraints I believe we would use tubes, utilising the length of the paper and creating a larger base for the structure. However, the team did still enjoy the idea of using the triangles and overall, our structure was very creative. Task 2: Choosing a Brief
