You can put this solution on YOUR website!
To graph $\"y=-x%5E2%2B2x\"$ , plug in a series of 'x' values to find the corresponding y values (eg plug in x=3 to get $\"y=-%283%29%5E2%2B2%283%29=-3\"$ giving the point (3,-3)). Once you have a series of points, you will get a parabola. Another way to do it is to find the vertex and then find points on either side of the vertex.\r
