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). WebOct 6, 2024 · To begin, we graph our first parabola by plotting points.
