document.write( "Question 764920: I have an upside down \"U\" parabola. I have two line segments that cross the parabola at perfectly even slope (y=a and y=b). How can I \"fit\" those lines into the parabola in a way where I can determine the distance between the line segments. Essentially, a minus b? Thanks! \n" ); document.write( "

You can put this solution on YOUR website!
The distance between the two lines is |a-b|.\r

\n" ); document.write( "\n" ); document.write( "Since your description is given without values to numbers, a general parabola \"y=Qx%5E2%2Bdx%2Bc\", and having a maximum point vertex would require that \"Q%3C0\". You can complete the square to find standard form of this parabola and find the vertex point. The y value of this vertex point must be greater than a and b.
