Quadratic modeling

[list=1] [*] Using matrix equations, find the quadratic function that models the situation (round to 4 decimals). [*] Using the "input" bar on the graph, graph your quadratic function. How does this compare to the curvature of the 2 hills? [*] Find the axis of symmetry using the following formula: x=-b/2a [*] Find the coordinate of the vertex by hand. How does this compare to the graph? [*] How could you find a more accurate function to model this parabola? Do it and graph the function. How does this compare to your original? [*] Print your screen, paste it into word and print (change to paper orientation to landscape if need be) ***make sure you are printing the parabola after inputting your function!!!*** [*] Put your name on your graph!!!!
