    Did you got done any of the math problems-the 2 pages of it that I gave you from Jaimie?
    I be waiting to check the math problems that you did, and then I may like to give you more worksheets (soon, after that).

    Here's the first one.  I'm working on the second one now.  I forgot how to do this stuff probably immediately after the finals in high school which was nine years ago.  Ugh   I guess I'll take my challenge failed now. 


     

    1A:

    lim of f(x) as x approaches 3 from the left = 5

    lim of f(x) as x approaches 3 from the right = 3² - 4 = 5

    The two-sided limit as x approaches 3 is 5.

     

    1B:

    lim of f(x) as x approaches -4 from the left = -4

    lim of f(x) as x approaches -4 from the right = 5

    -4 ≠ 5, therefore it’s discontinuous at x = -4 because the two-sided limit doesn’t exist.  It’s also discontinuous because there’s both a hole and a jump at x = -4.

    2A:

    2 - -1 = 3

    lim of f(x) as x approaches -1 from the left = 3

     

    2B:

    2 - -1 = 3
    -1

    3 ≠ -1, therefore the two-sided limit as x approaches -1 doesn’t exist.

     

    2C:

    lim of f(x) as x approaches -1 from the right = -1


    2D:

    0
    0

    The two-sided limit as x approaches 0 = 0

     

    2E:

    1

    lim f(x)  as x approaches 1 from the left is 1.

     

    2F:

    1
    (1 - 1)² = 0

    1 ≠ 0, therefore the two-sided limit as x approaches 1 doesn’t exist.

     

    2G:

    (1 - 1)² = 0

    lim of f(x) as x approaches 1 from the right = 0

     

    2H:

    0

    Livvie, I may need an Answer Sheet to help correct through this whole thing with, or it might take me really long to correct this with a good Scientific Calculator probably, maybe have to find something better than this if You want me to finish correcting this soon.

    1:

     (8 choose 5)(3x)⁵(-2)³

     coefficient of x⁵ = 56 x 243 x -8

    FINAL ANSWER:  -108864

     

     2:

             1

            1 1

           1 2 1

          1 3 3 1

         1 4 6 4 1

      1 5 10 10 5 1

    1 6 15 20 15 6 1

    1 7 21 35 35 21 7 1


    1 = (5a)⁷(b)⁰
    7 = (5a)⁶(b)¹
    21 = (5a)⁵(b)²
    35 = (5a)⁴(b)³
    35 = (5a)³(b)⁴
    21 = (5a)²(b)⁵
    7 = (5a)¹(b)⁶
    1 = (5a)⁰(b)⁷

     = 35 x 5³ x a³b⁴

     FINAL ANSWER: 4375.

     

     3:

     coefficient of a⁵b⁷

     (12 choose 5) = (12 choose 7)

    FINAL ANSWER:  792

     

     4:

     - (512/x18) + (2304/x15) - (4608/x12) + x⁹ + (5376/x⁹) - 18x⁶ - (4032/x⁶) + 144x³ + (2016/x³) - 672

     FINAL ANSWER:  -672

     

     5:

     (3x + 2y)⁴  

     = (3x)⁴ + (4 choose 1)(3x)²(2y) + (4 choose 2)(3x)²(2y)² + (4 choose 3)(3x)(2y)³ + (2y)⁴

     FINAL ANSWER:  81x⁴ + 216x³y +216x²y² + 96xy³ + 16y⁴

     

     6A:

     (1 +1)⁴

     = 2⁴

     = 1 + (4 choose 1)(1) + (4 choose 2)(1²) + (4 choose 3)(1³) + 1⁴

     ⇒ (4 choose 1) + (4 choose 2) + (4 choose 3)

     = 16 - 2

    FINAL ANSWER: 14

     

     6B:

     (1 + 1)⁹

     = 1 + (9 choose 1) + (9 choose 2) + (9 choose 3) + (9 choose 4) + (9 choose 5) + (9 choose 6) + (9 choose 7) + (9 choose 8) + 1

     ⇒ (9 choose 1) + (9 choose 2) + (9 choose 3) + (9 choose 4) + (9 choose 5) + (9 choose 6) + (9 choose 7) + (9 choose 8)

     = 2⁹ - 2

    FINAL ANSWER: 510

     

     7A:

    FINAL ANSWER: 10

     

     

    7B:

     (9 choose 6)3³x⁶(1/x⁶)

     FINAL ANSWER: 2268

     

     

    8:

     

    x³ is in (5 choose 3)(2)²(-x)³

     (5 choose 3) = 10

     The term is -40x³

     FINAL ANSWER:  The coefficient is -40.

     

     

    9:

     (7 choose 2)5²(2x²)⁵

     FINAL ANSWER: 16800x10

     

     

    10: 

    FINAL ANSWER: (2+ax)⁴ = 16 + 32ax + 24a²x² + 8a³x³ + a⁴x⁴

    Livvie, hope we'll able to find the answer sheet (from Google) for this-so I can correct these sheets soon if give the answer sheet to me after you find it(?)

    Umm, you're the teacher.  You don't need an answer sheet!  Expanding binomials and solving piecewise functions is fun so let's get grading here!  I wtk if Jaimie has to eat five gallons of ice cream when she gets back!  Also, she's Canadian so make sure she has to eat five imperial gallons of ice cream and not five USA gallons, please.

    Do you know how I will get through correcting all the rest of these (important math sheets) that Jaimie handled to me to give to you-soon, then I can work on the other drawing projects-for this answerMug site, and I think it would be really fun to draw these & for them & you to see these too-& I would like to start these soon(?)

    Have you heard anything from Jaimie from the last couple/few days?
    I have more things to type to Jaimie & would like to hear from Jaimie soon, and I will next give Jaimie other choices of topics/selections to pick & type messages about and to reply to me then to Jaimie about these(selection of choices)-I will make a new place thread just for Jaimie to type from these choices & for Jaimie to review the replies just from that new thread.
