Calculate the Y values corresponding to the X values given below. Find the critical values for X for the given polynomial by finding the X values among those given where the first derivative, dv/dx- 0 and/orn X values where the second derivative, d-y/dx2-0. Be sure to find the sign (+ or-) of dv/dx and of d'y/dx2 at all X values. Using the first and second derivative tests with the information you have calculated, determine which X value(s) represent maximums (MAX),...
Suppose you have a scatterplot representing 20 (X,Y) pairs. All of the values of X and Yare between -5 and 5. The correlation between X and Yiso. Which of the following (X, Y) pairs would result in a strong negative correlation if it were added to the scatterplot? Not enough information is given to determine an answer.
