Use a graphing calculator to plot the data and find the quadratic function of best fit.
-The number of housing starts in one beachside community remained fairly level until 1992 and then began to increase. The following data shows the number of housing starts since 1992 (x = 1) . Use a graphing calculator to
Plot a scatter diagram. What is the quadratic function of best fit? $\begin{array} { l | l } \text { Year, x } & \text { Housing Starts, H } \\\hline 1 & 200 \\2 & 205 \\3 & 210 \\4 & 240 \\5 & 245 \\6 & 230 \\7 & 220 \\8 & 210\end{array}$

The quadratic function of best fit for the given data, when plotted and calculated using a graphing calculator, typically results in a formula that closely matches the trend of the data points. Choice B, H(x) = -2.679x^2 + 26.607x + 168.571, correctly represents a quadratic equation that could model the given data, with a negative coefficient for the x^2 term indicating a parabolic shape that opens downwards, which aligns with the increase and subsequent decrease in housing starts as described.
