An economics study on job growth in a country after a revolution results in the data below. The x-value is the number of years after the revolution and the y-value is the percent of unemployment in the country each year. x y
8 6.3
11 7.7
14 8.6
17 9.0
20 14.0

Compute the least squares regression line modeling this data. What is the percent of unemployment in the country 0 years after the revolution? Round your answer to two decimal places.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
