Question: Business The table shows the number of personal computers (in thousands) sold in selected years:

1. Let \(x=0\) correspond to 1980 . Use \((5,3200)\) as the vertex and the data for 2000 to find a quadratic function \(f(x)=a(x-h)^{2}+k\) that models this data.
2. Let \(x=0\) correspond to 1980 and plot the data points. Use quadratic regression to find a function \(g\) that models this data. Based on the value of \(r^{2}\), how good a model is this?
3. Use the quadratic model from part (a) or (b) to estimate the number of computers sold in 1992 .
4. Assuming these models remained accurate, how many computers were sold in $2002 ?$

Price: $2.99
