Load the left- and right-hand sides of the given equation into Y1 and Y2 , re- spectively. Adjust the WINDOW para- meters until all points of intersection (if any) are visible in your viewing window. Use the intersect utility in the CALC menu to determine the coordinates of any points of intersec- tion. ii. Make a copy of the image in your viewing window on your homework paper. Label and scale each axis with Copyrighted material. See: 1 xmin, xmax, ymin, and ymax. Label each graph with its equation. Drop dashed vertical lines from each point of intersection to the x -axis, then shade and label each solution of the given equation on the x -axis. Remember to draw all lines with a ruler. iii. Solve each problem algebraically. Use a calculator to approximate any radi- cals and compare these solutions with those found in parts (i) and (ii). 13. x 2 = 5 14. x 2 = 7 15. x 2 = 7 16. x 2 = 3 17. x 3 = 6 18. x 3 = 4 19. x 4 = 4 20. x 4 = 7 21. x 5 = 8 22. x 5 = 4 23. x 6 = 5 24. x 6 = 9 In Exercises 25 - 40 , simplify the given radical expression. 25. 49 26. 121

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
