Question
THE first question is how to add vectors?

The second question is how to graph a quadratic equation?

Thanks

Answer
Usually you break each vector into its x and y components, add the x components, add the y components, and then recombine, since R^2 = x^2 +y^2.
If you have a specific example, send it in.
If you have a quadratic equation such as
y = ax^2 +bx +c, simply put in values for x, calculate y, and plot the x,y values.
