On what interval(s) is the function DECREASING? 12. On what interval(s) is the function CONCAVE UP? 13. Give the exact VALUES of the RELATIVE EXT REMA and‘teil WHERE THEY OCCUR: (Make sure you tell which are MINIMA and which are MAXIMA.) 14. Give the exact VALUES of the INFLECTION POINTS and tell WHERE THEY OCCUR: 15. Are there any ABSOLUTE extrema? If so, give both x and y-values: FIND THE FOLLOWING INTEGRALS: 3 2 16. x -:lx-8 dx 17. X2+2 dx x(x +4) x-1 2 SOLVE THE STORY PROBLEM. NOTE: Volume of a sphere is V = 4I3’fl" r 3 18. The radius of a balloon is DECREASING at a rate of - 2 cm/sec. How fast is the VOLUME of the balloon changing when the radius is 10 cm? (Make sure to label your answer with units.) GIVEN THE GRAPH SHOWN HERE, SET UP THE INTEGRALS BELOW. CURVE I:/y=-x+4 CURVE ll: x=1 DO NOT EVALUATE THE INTEGRALS... SET UP ONLY. 19. An integral with respect to X that gives the AREA of the shaded region. 20. An integral which gives the VOLUME generated when rotating the shaded region around the Y-AXIS using DISKS or WASHERS. 21. An integral which gives the VOLUME generated when rotating the shaded region around the X—AXIS using CYLINDRICAL’SHELLS. 22. An integral which gives the VOLUME generated when rotating the shaded region around the X—AXIS using DISKS or WASHERS. BONUS PROBLEM: (Show work below.) YOU MUST SHOW WORK BY HAND FOR CREDIT. EVALUATE the integral in #2l . and #22 to show that they are EQUAL. ...
