![]() ![]() Substituting this back into either (1) or (2) gives: ![]() Next, substitute (-3, -4) and (3, -4) to give 2 equations in 2 unknowns: We have 3 points and 3 unknowns, so we just substitute them in: One is to recall the general form for a parabola: I can find the equation for this parabola in several different ways. I know the equation for my parabola will have a negative in front, since it is inverted (upside-down). So my aim is to find the parabola that passes through the Origin (0, 0) and the points (-3, -4) and (3, -4). We can see the resulting points (in magenta color) in the next image. Next, determined the values of y for xranging from -3 to 3. Model the arch using a parabola and see how well it fits.ĭrew a set of x-y axes and a regular grid on top of the photograph. The Gateway Arch “is really a monument to the 20th century and to the height of American power,” says historian Tracy Campbell. The monument opened to the public on June 10, 1967.
