Essay

Write the word or phrase that best completes each statement or answers the question.
-The table shows the winning time for the women's 200 -meter run at seven consecutive summer Olympic Games.

Let $\mathrm{x}=1$ correspond to 1960 and let $\mathrm{f}(\mathrm{x})$ be the winning time for the women's 200 -meter run at the Olympics in year $x$ . Using the points $(1,24.0)$ and $(25,21.81)$ , the following linear function is obtained to model the data: $f(x)=-0.09125 x+24.09125$ . According to this model, will the winning time ever reach 10 seconds? If so, when? Do you think that it makes sense to use the model to make predictions for future years?
