1) two make-ups get 40 and 70\n2) make-ups get 68 (current mode)\n3) denote the score of one make-up student as x, write out the mean, set it equal to 58 and solve the equation (it is your homework, remember?)

Checking by method of differences\n\n. x ............. f(x) ...... Δ1 ...... Δ2\n. 0 .......... 1104\n. 1 .......... 1104 ........ 0\n. 2 .......... 1100 ........ 4 ....... -4\n. 3 .......... 1092 ........ 8 ....... -4\n. 4 .......... 1080 ...... 12 ....... -4\n. 5 .......... 1064 ...... 16 ....... -4\n. 6 .......... 1044 ...... 20 ....... -4\n. 7 .......... 1020 ...... 24 ....... -4\n. 8 ............ 992 ...... 28 ....... -4\n. 9 ............ 960 ...... 32 ....... -4\n10 ............ 924 ...... 36 ....... -4\n11 ............ 884 ...... 40 ....... -4\n12 ............ 840 ...... 44 ....... -4\n13 ............ 792 ...... 48 ....... -4\n14 ............ 740 ...... 52 ....... -4\n15 ............ 684 ...... 56 ....... -4\n16 ............ 624 ...... 60 ....... -4\n17 ............ 560 ...... 64 ....... -4\n18 ............ 492 ...... 68 ....... -4\n19 ............ 420 ...... 72 ....... -4\n20 ............ 344 ...... 76 ....... -4\n21 ............ 264 ...... 80 ....... -4\n22 ............ 180 ...... 84 ....... -4\n23 .............. 92 ...... 88 ....... -4\n24 ................ 0 ...... 92 ....... -4\n\nSo the relation is quadratic (as Δ2 is constant which imples the 2nd derivative is constant)\n\nSo the relation is of the form\n\nf(x) = ax^2 + bx + c\n\nNow f(0) = c = 1104\nf(1) = a + b + c = 1104\nSo a + b + 1104 = 1104\nie a + b = 0\n\nf(2) = 4a + 2b + c = 1100\n4a + 2b + 1104 = 1100\nSo 4a + 2b = -4\n\nie 2a + 2a + 2b = 2a + 2(a + b) = -4\nSo 2a + 0 = -4\nie a = -2 and b = 2\n\nThus f(x) = -2x^2 + 2x + 1104\n= -2(x^2 - x - 552)\n= -2(x - 24)(x + 23)\n\nTest f(10) = -2*(10 - 24)(10 + 23)\n= -2 * (-14) * (33)\n= 28 * 33\n= 924 YESSSSSSSSSSS!!

I compiled a list of great calc sites. You may want to check out MIT opencourseware too.

practice xtra hard 4 commerce related topics.nd 4 others like calculus  ur formulae shud alwz b clear nd on ur tips.nd 4 limits reason out nd think.and wat else practice nd practice..and thats da key 2 100% mks in maths.dis is my experince.believe me.

The Edifier has it right, but darned if I can follow the notation. You really need to see this written out like a textbook to understand what's going on.\n\nClick the link below in "sources" to see the answer hosted at my website www.calculus-help.com. Right now, Yahoo! answers, as far as I can tell, doesn't allow graphics, which makes it tricky to answer ANY math questions.\n\nPlease don't post math answers, guys, if the poster knows the answer but can't get there, and you get something completely different.

I think a calculator would be great for this one! It sounds perfect for a math wiz to try...Good luck! MayMay

wouldnt it be like 3<x<-3 f(x)\nso like x would be 1 so it would be just f if you really want to simply that far done.

If you look at a picture (aka a graph) of the function, it will all become clear...\n\nhttp://upload.wikimedia.org/wikipedia/en/3/3e/1-over-x.png

to get an extra credit, maybe?\n\n---\n\nseriously, I cannot figure out how you can study calculus without knowing limits: even if you only deal with numerical procedures, every iterative formula, or better, EVERY FORMULA (such as those used to find the roots of a non-linear equation, approximated integrals, derivatives and so on) needs a preventive study for convergence conditions: this involves limits!\n\nOne more step back: DERIVATIVE IS A LIMIT ! How can you apply it without knowing what it is?

I am studying for the AP Calclus test right now and I am as ready as I will ever be.  It is my language test (AP Spanish) that I feel unprepared for.  I just suggested this to someone else for AP Calc so I will tell you too, study:\n\nsolids of rotation (disc, washer, and shell), the fundamental thereom of Calculus (what integral means), U-substitution, derivative rules, Riemann sums, speed, linearization (finding the slope of the tangent line), volume of known cross sections, concavity and inflection points, the area between two curves, differentiability and continuity, local and global extrema (critical points and end points), implicit differentiation equations, trignometric derivatives, the rule of exponential growth (like volume increasing at a rate proportional to the radius), average value of a function, optimization, and related rates. \n\nI know that is a lot but I have taken 5 complete practice AP tests (former tests) in class since February and all of these concepts were reccuring.

by inspection I can understand another point will be...\n\n(0, 5) because if you add 1 to X you must add 2 to Y
