-4y^2+2y-9 eching

$$- 4 y ^ { 2 } + 2 y - 9$$

y ga nisbatan hosilani topish

$$2-8y$$

Yig'indi uchun derivativ qoidasidan foydalanish qadamlari

Polinomialning hosilasi bu uning shartlari hosilasining yig‘indisiga teng. Konstant shartning hosilasi 0. ax^{n} ning hosilasi nax^{n-1}.

$$2\left(-4\right)y^{2-1}+2y^{1-1}$$

2 ni -4 marotabaga ko'paytirish.

$$-8y^{2-1}+2y^{1-1}$$

2 dan 1 ni ayirish.

$$-8y^{1}+2y^{1-1}$$

1 dan 1 ni ayirish.

$$-8y^{1}+2y^{0}$$

Har qanday t sharti uchun t^{1}=t.

$$-8y+2y^{0}$$

Har qanday t sharti uchun (0 bundan mustasno) t^{0}=1.

$$-8y+2\times 1$$

Har qanday t sharti uchun t\times 1=t va 1t=t.

$$-8y+2$$

Baholash

$$-4y^{2}+2y-9$$
