Question 263098
To graph {{{y=-x^2+2x}}}, plug in a series of 'x' values to find the corresponding y values (eg plug in x=3 to get {{{y=-(3)^2+2(3)=-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.



To find the y-intercept, plug in x=0 and solve for y.



To find the x-intercept, plug in y=0 and solve for x. To do this, either factor or use the quadratic formula.
