WebbThe following are sketches of the graphs of the functions in the form y = axn + c , where n = –2, –1, 1, 2 and 3. Take note of their general shapes and positions in relation to the x -axis and y -axis. These are some basic graphs that every algebra student should know. 1. y = mx + b (Linear Function) 2. y = x2 (parabola) 3. y = xn WebbUse the symmetry of the graph to find the coordinates of the turning point of the following quadratic: Step 1: Factorise the quadratic, setting it to zero to find the locations of the roots. Solving we get the following roots. Step 2: Find the x x coordinate. Therefore, the x x coordinate must be \textcolor {green} {1.5} 1.5.
