Please show all work including algebra. Thank you.

10 a Define second derivative test Find all relative extrema using Second derivative test for ( i ) f(x ) = - 30 + 5 x ( ii ) fire) = 2 - 32 x + 12 (iii ) fin ) = re - 4 vx + 1 Analyze and sketch the graph of the function Label any intercepts , relative extrema, points of inflection and asymptotes . show tables clearly first and second derivative test clearly as shown in the worked out examples in the book as well as in my videos . Do not use graphing calculator to graph. NO work - No Points policy Show all Your work clearly to get points. If you answer just graphing using graphing calculator you will not get any Points . These two problems carries lot of points. 5 a fox) = - 5x ( b ) = 4
