Name: Assign 4.4 Graphing MATH 2413 For the problems below, take the values of A and B as the last two digits of your Blinn ID that are not 0 or 1. A=5 B=8 1. Given the function f(x)=84x-5Ax* -20 Ax + B, find all 1st and 2nd order critical values, build sign charts for both the 1st and 2nd derivative, determine the intervals where the function is increasing, decreasing, concave up or concave down, find all local minimum and maximum points and all inflection points and use this information to obtain an accurate graph. Any numerical value that is nit exact may be rounded to the nearest 0.1.
