Āhuatanga te ako mō te tīmata

Taumahi ki te momotuhi huaina he wāhi ōrite, e hāngai ana ai te ia tau x i te huinga ngā he maha etahi o rawa y.

Kei te nuinga o te wā Taumahi denoted e pukapuka Latin. A feruri i tetahi tauira f. Te tau y, e hāngai ana ki te maha o te x, ka karanga te uara f homai i te wāhi x motuhake. He rite: f (x). Ko te rohe o te mahi f - ko D (f). Ko te wāhi i ngā o ngā uara katoa o te f pānga (x), i reira te x tautohe i roto i te rohe o te rohe i huaina uara f. Ia i tuhituhia rite: E (f).

I roto i te nuinga o te wā, te mahi whakaturia e te tātai. Ko te kupu, ki te kore tautuhi atu mahi herenga rohe ti'araa, tautuhia nei i te tātai, ka kia whakaaro rite te huinga o ngā uara tāupe, a kei te tango taua tātai wahi.

Ko te uniana o ngā huinga e rua ko te huinga, i ia huānga o e kia no ka no ki te iti rawa tetahi o nga huinga raraunga.

Hei tohu i te tau ki te mahi rohe ti'araa x etahi pukapuka tīpakohia, ka karanga tāupe motuhake tautohe ranei.

te wāhi i roto i nei e kore te e maha kitea huinga tau te whānuitanga o ngā uara me te ti'araa rohe.

A, no te Ko te ako o te mahi, e taea te kite i tauira ki te awhina o whakairoiro. Kauwhata o te mahi ko te huinga o ngā i runga i te waka rererangi fakafekau'aki, te wahi i te tautohe "rere" te wāhi whakaritea katoa. Hoki ko te huinga o te waka rererangi taururuku kauwhata o te pānga, ko reira e tika ana e te huinga i te iti rawa kia kotahi wāhi i roto i te noa ki tetahi whakarara raina ki te abscissa.

karanga Taumahi ki te huinga tipu ki te hāngai te uara teitei o te tautohe ki te taua uara i whakaritea ki te mahi teitei, me te heke i te huinga - ki te hāngai te uara teitei o te tautohe ki te uara i raro o te mahi.

I roto i te mahi rangahau i runga i te ara, me te i runga i te heketanga o te hiahia ki te tautapa i wā o te tipu me te heke o te roa mōrahi.

huaina te mahi ko te mamaoa ki te, mo tetahi tautohe ki tona ti'araa rohe ki hono f (-x) = f (x), ranei unpaired - ki te hoki tetahi tautohe ki te momotuhi rohe he f (-x) = - f (x). Haunga, ka hei te kauwhata pānga rua whanaunga hangarite ki te tuaka-y, a he kauwhata unpaired - hangarite e pā ana ki te wāhi (0, 0).

I roto i te tikanga ki te karo hapa ka kawea te mahi i roto i te ako, me ako koe ki te kitea te āhuatanga āhuatanga. Ki te mahi i tenei, me mahi e koe i te whai i ēnei:

1. Kimihia te ti'araa rohe.

2. Te whakahaere i roto i te haki i runga i te pairing unpaired ranei, me te auau.

3. Ko reira e tika ana ki te kitea te wāhi o te kauwhata o te reticle ki whakarite me te abscissa.

4. I tenei wāhi, e hiahia ana koe ki te kitea i te wā i reira te mahi kua he uara tōrunga, me te wahi - tōraro. E huaina ēnei wā wā ki tonu tohu. Ko, e hiahia ana koe ki te whakatau i te wahi ko te hōtaka - i runga ranei i raro i te tuaka x-.

5. nui whakahaere i te mahi o te hanga raraunga i runga i te kauwhata e te tipu i te tahi mau wāhi mahi, me etahi heke. ka karanga taua āputa wā mokowā o tupu me te uri.

6. Na e hiahia ana koe ki te kitea te uara o te mahi i te ngā i reira whakakapia te tupu e na roto i te uri, ranei hurihia.

hanga he mahi taua ako e taea ki te whakaaro i te kauwhata. I tua atu, he mea e tika ana ki te kitea te wāhi o te tino. He aha te mea te reira?

Ko te wāhi ko te wāhi iti, ki te hoki ngā uara katoa o te tautohe ki te tetahi wāhi ngā ka kia tika te ōritenga f (x)> f (x0).

Ko te wāhi ko te wāhi mōrahi, ki te hoki ngā uara katoa o te tautohe ki te tetahi wāhi ngā ka kia tika te f ōritenga (x)
