求反函数 13+sqrt(3x-3)

解答

求反函数

13 + 3 x - 3

\frac{x ^{2} - 26 x + 172}{3}

求解步骤

y = 13 + 3 x - 3

用

y

替代

x

x = 13 + 3 y - 3

求解

y, x = 13 + 3 y - 3

\frac{x ^{2} - 26 x + 172}{3}

in v erse \frac{4 + h - 2}{h}

in v erse f (x) = \frac{2 x}{x - 6}

in v erse \frac{d}{d} (3 \frac{1}{4 x ^{2}})

in v erse f (x) = y^{2} - 8 y

in v erse f (\frac{x + 2020}{x + 2022}) = x + 2021
