Easy peasy! Just plug different x-values into your quadratic equation y = ax^2 + bx + c and solve for y. Each pair of (x, y) will be a point on the graph.
Honestly, graphing software does this in seconds. Why do it manually?
From personal experience, plotting points manually helps you truly understand how the parabola behaves. Pick several x-values, sub in, and chart those y-values!
Just use the formula y = ax^2 + bx + c with various x values. You get (x, y) points for each x.
