WebApr 9, 2009 · Hi Zach. Since y^2 = x − 2 is a relation (has more than 1 y-value for each x-value) and not a function (which has a maximum of 1 y-value for each x-value), we need to split it into 2 separate functions and graph them together. So the first one will be y 1 = √ (x − 2) and the second one is y 2 = −√ (x − 2). WebSketch two parabolas here on each grid, using the dots for each parabola’s vertex. Notice the scale! The nice thing about this method is that you can use it to draw other kinds of parabolas, ones that have been stretched or compressed. For example, for the parabola, the 2 means that the parabola is twice as steep as a “normal” one, so you ...
