逆 f(x)=-0.941x^2+52.38x+1

解

逆

f (x) = - 0.941 x^{2} + 52.38 x + 1

- \frac{- 52380 + 5238 0 ^{2} + 3764 ( 1000 - 1000 x )}{1882}, - \frac{- 52380 - 5238 0 ^{2} + 3764 ( 1000 - 1000 x )}{1882}

解答ステップ

y = - 0.941 x^{2} + 52.38 x + 1

x

を以下で置き換える:

y

x = - 0.941 y^{2} + 52.38 y + 1

y

を解く

x = - 0.941 y^{2} + 52.38 y + 1

- \frac{- 52380 + 5238 0 ^{2} + 3764 ( 1000 - 1000 x )}{1882}, - \frac{- 52380 - 5238 0 ^{2} + 3764 ( 1000 - 1000 x )}{1882}
