Read: Sections 2.1 and 2.2 either before you begin the assignment or when you get to the last question. Do: Estimate the slope of the graph of the function at the point using the two-sided estimate, as in Monday's class. For the functions in exercises 1-3 estimate the slope again using a one-sided estimate, as in the textbook (either side, but the right side 1) f(x) = x^2 at the "point" x = 3 2) f(x) = x^3 at the "point" x = -- 2 (that's minus 2) 3) f(x) = square root of x at the "point" x = 9 4) f(x) = x^2 - 5x + 7 at the "point" x = 1 5) f(x) In(x) at the "point" x = 3 Remember to estimate the slopes of the graphs in exercises 1-3 using two methods: a two-sided estimate and a one-sided estimate.

Several states have argued that the 65-mph speed limit has no justification and have refused to enforce it. The federal Department of Transportation (DOT) believes that the 65-mph limit saves lives. To illustrate its contention, the department regressed the number of traffic fatalities (Y) last year in a state on the state’s population (X1), the number of days of snow cover (X2), and the average speed of all cars (X3). The results are shown below. Table 10: Model Summary Model R R Square Adjusted R Square Std. Error of the Estimate 1 .821 a .780 .613 3.258 a.

A major software company is considering a price increase on its most popular product.   They are currently selling below their competitor’s price. Someone from the Brand team suggested they check consumer response before making a price increase. You are called into explain how this marketing research might be carried out.  In terms of qualitative and quantitative options you tell them...
