Graph the quadratic function y = x2 + 6x + 8 %3D 1) Evaluate the y values in the table below (show your work) y = x2 + 6x + 8 -6 -5 -4 -3 -2 -1 2) Using graph paper (if you have it), plot all 7 points from the table of values. If you do not have graph paper, you will have to measure the units carefully. (Go get some graph paper for subsequent assignments!!) 3) Connect the dots in the shape of a parabola (remember, it's a bit rounded). 4) Draw a dashed vertical line through the vertex. (You may use a different color, if you wish.) 5) Fold your paper along the line of symmetry to ensure that the parabola is symmetrical.

The ways of recognizing a quadratic function
A penny is thrown from the top of a 48.9-meter building and hits the ground 3.04 seconds after it was thrown. The penny reached its maximum height above the ground 0.79 seconds after it was thrown. Define a quadratic function, h, that expresses the height of the penny above the ground (measured in meters) as a function of the number of seconds elapsed since the penny was thrown, t. What is the maximum height of the penny above the ground?

The purpose of this analysis is to model available atmospheric carbon dioxide data with a quadratic function of the form f(x) = ax2 + bx + x. In the space below, type the model quadratic function for the relationship between year and mean carbon dioxide levels in standard mathematical form using the coefficients calculated on the spreadsheet. Using the model equation, determine the mean atmospheric carbon dioxide levels in the year 2030. Using the model equation, determine the mean atmospheric carbon dioxide levels in the year 2050. What other factors might need to be taken into account to provide a more robust model to make predictions regarding future atmospheric carbon dioxide levels?
