Translations involve shifting a graph horizontally or vertically without altering its shape. A horizontal translation of *f(x)* by *a* units is represented as *f(x - a)*, shifting the graph to the right if *a* is positive and to the left if *a* is negative. Vertical translations are achieved by adding or subtracting a constant *b* to the function, *f(x) + b*, moving the graph upwards if *b* is positive and downwards if *b* is negative. Mastering these translations is essential for accurately sketching transformed graphs in your Singapore junior college 2 H2 math exams. Remember, these transformations affect the coordinates of key points on the graph, such as intercepts and turning points.
Reflections create a mirror image of the graph across a specific axis. Reflecting *f(x)* across the x-axis involves negating the entire function, resulting in *-f(x)*. This flips the graph vertically. Conversely, reflecting across the y-axis involves replacing *x* with *-x*, yielding *f(-x)*, which flips the graph horizontally. Understanding reflections is crucial, as they often appear in combination with other transformations. Singapore junior college 2 students should practice identifying invariant points (points that remain unchanged after the transformation) during reflections to ensure accuracy.
Stretches and compressions alter the dimensions of the graph. A vertical stretch or compression is represented by *a* *f(x)*, where *a* is a constant. If *a* > 1, it's a vertical stretch; if 0 1, it's a horizontal compression; if 0
Many exam questions involve a combination of transformations. The order in which transformations are applied matters, especially when dealing with stretches/compressions and translations. A common approach is to address stretches/compressions first, followed by reflections, and finally translations. To avoid mistakes, consider applying the transformations step-by-step and carefully tracking how each transformation affects key points on the graph.
