Just solve 3b

3. Consider the data 32 6 2 021 7 (a) Using a Table of Divided-Differences (by hand), construct the Newton interpolating polynonial for the data. Based on the polynomial, what value would y have when r =-2? (b) Using Matlab's M-lile for the Newton interpolating polynomial from the Lab, check your estimate for y in (a) when r =-2. Include a printout of the Matlab code used, or write the commands and resulting output out by hand. There is no need to print or write out the Newton interpolating poly M-file unless you have changed it. Just write/print out the commands used to obtain the estimate for y
