The St. Louis Arch is in the shape of a hyperbolic cosine function It is often thought that it is in the shape of a parabola, which would have a quadratic function of y = a(x-h)^2 + k, where the vertex is h, k.
St. Louis Arch is an example of a quadratic graph. Umm... many arches are actually *catenaries*, visually indistinguishable from a parabola - this answer should be checked for accuracy.
The range of a function when you consider a graph is how high and how low it goes. A quadratic function is usually an arch that goes up to a high point and then back down like the arch of a kicked ball. Or, it can be the reverse which goes down and then up in a mirror image of a kicked ball. The range is what y values would be needed to show ALL the graph. Example; y=x^2+5x-6 The graph crosses the x axis at -5 and 1 it goes down then back up. The range is from infinity down to -49/4

The St. Louis Arch
St. Louis ARCH symbolizationThe St. Louis arch symbolizes the gateway to the west. In the late 1800's and early 1900's, St. Louis was considered the west. Builders constructed the arch to symbolize St. Louis as the city of the west. back then, it was known as St. Louis being the west; the territory beyond was being explored by Louis and Clark at the time the arch was built. It took over 2 years to construct the arch, or otherwise called, the St. Louis Gateway.
Construction on the Gateway Arch in St. Louis was completed in 1965.
The Gateway Arch in St Louis
The Official name of the St. Louis Arch is the Jefferson National Expansion Memorial. It is often called the Gateway arch.
St. Louis You would find the Gateway Arch in St. Louis.
A parabola. An arch opening either north or south of the x-axis depending on the sign of the coefficient (negative opens down, positive opens up).
How did the indians build the arch
No, no one died in the building of the arch.
