(a) The graph of y = f(x) is transformed to the graph of y = 2f(x − 1). Describe fully the two single transformations which have been combined to give the resulting transformation. (b) The curve y = sin 2x − 5x is reflected in the y-axis and then stretched by scale factor 1/3 in the x-direction.
16 mar 2023 · How do we describe reflections of graphs? Some questions give a transformed function in the form y = f(−x) or y = −f(x) and ask you to describe the transformation; To describe a reflection fully, you must include; the transformation: "reflection" the direction; in the x-axis or in the y-axis; Remember that
20 kwi 2023 · What do I need to know about graph reflections? The graph of y = -f(x) is a reflection in the x axis The x coordinates of points stay the same; y coordinates have their signs flipped (positive to negative, negative to positive) Points on the x axis stay where they are; All other points are reflected to the other side of the x axis
Reflection of a graph in the x-axis makes the y-coordinates switch signs. For instance, if you have the point (2, 3) in the original graph, it will become (2, -3) in the reflected graph. Reflecting a graph in the y-axis leads to inversion of the sign of the x-coordinates.
Here we will learn about graph transformations, including translating vertically, translating horizontally and reflecting in the coordinate axes. There are also graph transformation worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck. What are graph transformations?
Graph functions using reflections about the [latex]x[/latex] -axis and the [latex]y[/latex] -axis. Determine whether a function is even, odd, or neither from its graph.
