逆 f(x)=0.1061x^2-0.3145x-10.832

解

逆

f (x) = 0.1061 x^{2} - 0.3145 x - 10.832

\frac{0.3145 + 0.4244 x + 4.69601105}{0.2122}, \frac{0.3145 - 0.4244 x + 4.69601105}{0.2122}

解答ステップ

y = 0.1061 x^{2} - 0.3145 x - 10.832

x

を以下で置き換える:

y

x = 0.1061 y^{2} - 0.3145 y - 10.832

y

を解く

x = 0.1061 y^{2} - 0.3145 y - 10.832

\frac{0.3145 + 0.4244 x + 4.69601105}{0.2122}, \frac{0.3145 - 0.4244 x + 4.69601105}{0.2122}
