From measurements I'm having 4 sets of pressure and corresponding flow Plotted in a XYplot, the curve follows the form y=ax2bx, where y is the pressure and x is the flow I need to get the values of a and b, and R2 The curve have to cross in x,I mean, given the focus x, y and directrix (I'll use a horizontal line for simplicity) y = k you can find the equation of the quadratic;The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry The axis of symmetry has the equation x=−b2a

The general form of a quadratic is "y = ax2 bx c" For graphing, the leading coefficient "a" indicates how "fat" or how "skinny" the parabola will be Parabolas always have a lowest point (or a highest point, if the parabola is upsidedown) This point, where the parabola changes direction, is called the "vertex"By definition, the ycoordinate of points lying on the xaxis is zero Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax 2 bx c = 0 We can do this by completing the square as, Solving for x and simplifying we have, Thus, the roots of a quadratic function are given by,How do you do this backwards?
