He aha ke ʻano o kahi hana

Ma kēia hoʻolaha, e noʻonoʻo mākou i ke ʻano o kahi hana, pehea i koho ʻia a kuhikuhi ʻia. Hoʻopaʻa inoa mākou i kēia mau wahi no nā hiʻohiʻona kaulana loa.

Ka manaʻo o ka laulā

Domain he hoʻonohonoho waiwai x, kahi i wehewehe ʻia ai ka hana, ʻo ia hoʻi, aia y. I kekahi manawa kāhea ʻia wahi hana.

• x - hoʻololi kūʻokoʻa (hoʻopaʻapaʻa);
• y – dependent variable (hana).

Notation maʻamau o kahi hana: y=f(x).

Launch he pilina ma waena o nā mea hoʻololi ʻelua (sets). I ka manawa like, kēlā me kēia x hoʻokahi wale nō waiwai kikoʻī y.

ʻO ka wehewehe geometric o ke kikowaena o ka wehewehe ʻana o kahi hana, ʻo ia ke kuhi o ka pakuhi e pili ana me ia ma ke koʻi abscissa (0x).

Hoʻonohonoho o nā waiwai hana - nā waiwai a pau yʻae ʻia e ka hana ma kāna kikowaena. Mai ka manaʻo o ka geometry, ʻo ia ke kuhi o ka pakuhi ma ke axis y (0y).

Ua kuhikuhi ʻia ke kahua o ka wehewehe ʻana D (f). Ma kahi o f, i kēlā me kēia, hōʻike ʻia kahi hana kikoʻī, no ka laʻana: D(x²), D(hele x) etc.

A laila kau ʻia kahi hōʻailona like a kākau ʻia nā waiwai kikoʻī:

1. Ma o kahi semicolon, hōʻike mākou i nā palena hema a me ka ʻākau o ka wā e pili ana i nā waiwai ma ke axis. 0x (ʻoi loa ma kēlā kauoha).
2. Inā ʻo ka palena i loko o ka wehewehe ʻana, e kau i kahi pale huinaha ma ka ʻaoʻao, a i ʻole, he pale pōʻai.
3. Inā ʻaʻohe palena hema, kuhikuhi mākou "-∞", akau - "∞" (heluhelu ʻia ʻo “minus/plus infinity”).
4. Inā pono, inā makemake ʻoe e hoʻohui i kekahi mau pae, hana ʻia kēia me ka hoʻohana ʻana i kahi hōʻailona kūikawā “∪”.

ʻo kahi laʻana:

• [3; 10] ʻo ia ka hoʻonohonoho o nā waiwai āpau mai ʻekolu a hiki i ka ʻumi;
• [4; 12) - mai ʻehā a i ʻumikūmālua wale nō;
• (-2; 7] – mai ka emi ʻelua a i ka hui pū ʻana me ʻehiku.
• [-10; -4) ∪ (2, 8) – mai ka emi ʻumi a i emi ʻehā wale nō a mai ʻelua a ʻewalu wale nō.

'Ōlelo Aʻo:

• Ua kākau ʻia nā helu a pau i ʻoi aku ma mua o ka zero penei: (0; ∞);
• ʻino nā mea a pau: (-∞; 0);
• Helu maoli a pau: (-∞; ∞) ole 'ole R.
