System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
Consider the quadratic function y=-x² +6x- 2..
(a) Graph the function on the grid to the right.
The line y=9x-4 intersects the quadratic function y=x2+7x-3 at one point. What are
the coordinates of the point of intersection?

A human slingshot was used to launch a stunt man into the air across two football fields where he landed into a safety foam pit which was ground level. The trajectory of the stunt man can be modeled by the equation h(t)=-16t^2+144t, where h(t) is height in feet and t is time in seconds (if air resistance is neglected) How long will it take the stunt man to reach the ground?
