you want to compare two functions, you can use the graphing calculator. You can also use the graphing calculator to plot the graph of one or more functions of x. Enter equations like y = x^2 - 3 or sin(x), and the calculator plots them on an interactive grid you can zoom and pan so the axes and grid always rescale to what you are looking at. Any expression the scientific calculator understands works here — polynomials, trigonometry, logarithms, exponentials, roots and combinations — and each function you add is drawn inadistinctly colour so several curves can be compared on one grid. You can use the graphing calculator to plot the graph of one or more functions of x.

ຄໍາຖາມທີ່ຖາມເລື້ອຍໆ
ຂ້ອຍຈະເຂົ້າເຖິງຟັງຊັນໄດ້ແນວໃດ?
ພິມຕົວອັກສອນໃນ x, ເຊັ່ນ x^2, sin( x) ຫຼື 2*x+1, ເຂົ້າໃນເຄື່ອງຄິດໄລ່ກາຟິກ. ທ່ານສາມາດເພີ່ມຟັງຊັນຫຼາຍໆຕົວ ແລະ ແຕ່ລະຕົວຈະຖືກແຕ້ມດ້ວຍສີທີ່ແຕກຕ່າງກັນ.
ຂ້ອຍສາມາດປົດລັອກໄດ້ບໍ?
ຍອມຮັບ. ກົດ ຫຼື ໃຊ້ປຸ່ມປ້າຍເພື່ອປ້າຍອອກ ແລະ ດຶງກຣາຟເພື່ອປັ່ນໄປມາ. ແກນ ແລະ ຕາຕະລາງຈະປັບຂະໜາດຄືນໂດຍອັດຕະໂນມັດ.
ຕົວອັກສອນໃດທີ່ຂ້ອຍສາມາດແຕ້ມໄດ້?
ທຸກຄຳເວົ້າທີ່ການຄິດໄລ່ວິທະຍາສາດສະໜັບສະໜູນ - polynomials, trig, logs, exponentials, roots ແລະການລວມເອົາພວກມັນ.
ວິທີການທີ່ຂ້ອຍຈະວາງແຜນຟັງຊັນສອງຢ່າງເພື່ອຊອກຫາບ່ອນທີ່ພວກມັນຕັດກັນ?
ເຂົ້າເຖິງຟັງຊັນແຕ່ລະອັນໃນເສັ້ນຂອງມັນ, ຕົວຢ່າງ y = x^2-3ແລະ y = x - 1. ເສັ້ນໂຄ້ງທັງສອງຖືກແຕ້ມຢູ່ໃນກຣາຟດຽວກັນ, ແລະ ຈຸດທີ່ພວກມັນຜ່ານກັນ ແມ່ນວິທີແກ້ໄຂທີ່ເໝາະສົມກັບການສະແດງອອກສອງຢ່າງທີ່ເທົ່າກັນ.
ວິທີການທີ່ຈະແຕ້ມກຣາຟປາຣາໂບລາ ເຊັ່ນ y = x^2 -3?
ພິມ x^2 -3ເປັນຟັງຊັນ. ຜົນໄດ້ຮັບແມ່ນປາຣາໂບລາ U-shaped ທີ່ມີຈຸດສູງສຸດຢູ່ (0, -3); ຂະຫຍາຍ ຫຼື ວາງເພື່ອເບິ່ງບ່ອນທີ່ມັນຜ່ານເສັ້ນຜ່າສູນກາງ x ໃກ້ກັບ ±1. 73.
ຂ້ອຍສາມາດແຕ້ມຕົວເລກຕົວອັກສອນໄດ້ບໍ?
ແມ່ນແລ້ວ. ເຂົ້າໄປໃນ sin(x), cos(x) ຫຼື tan(x) ແລະ ເສັ້ນລົມຈະຖືກແຕ້ມຜ່ານໜ້າຈໍ. ລວມພວກມັນເຂົ້າກັນກັບຂໍ້ກຳນົດອື່ນໆ, ເຊັ່ນ sin(x) + x/2, ເພື່ອເບິ່ງຮູບທີ່ລວມກັນໄດ້.
ເຮັດຫຍັງກຣາຟຂອງຂ້ອຍເບິ່ງຄືວ່າບໍ່ມີຫຍັງ ຫຼື ບໍ່ມີພື້ນທີ່?
ເສັ້ນໂຄ້ງອາດຈະຢູ່ນອກການເບິ່ງປັດຈຸບັນໄດ້. ຖອດການປຽບທຽບ ຫຼື ຖອດການປຽບທຽບຈົນກວ່າຈະເຂົ້າເຖິງຂອບເຂດ - ສຳລັບຟັງຊັນທີ່ສູງ ຫຼື ທີ່ມີຄ່າສູງ ທ່ານມັກຈະຕ້ອງຖອດການປຽບທຽບອອກຈາກເສັ້ນຜ່າກາງ y ເພື່ອເບິ່ງຮູບທັງໝົດ.
ຜົນໄດ້ຮັບແມ່ນຄາດຄະເນສໍາລັບຄໍາແນະນໍາທົ່ວໄປເທົ່ານັ້ນ, ບໍ່ການເງິນ, ຄໍາແນະນໍາທາງການແພດຫຼືພາສີ.
