求反函数 16x^2+1

解答

求反函数

16 x^{2} + 1

\frac{x - 1}{4}, - \frac{x - 1}{4}

求解步骤

y = 16 x^{2} + 1

用

y

替代

x

x = 16 y^{2} + 1

求解

y, x = 16 y^{2} + 1

\frac{x - 1}{4}, - \frac{x - 1}{4}

in v erse f (x) = 4 x + x

in v erse f (x) = 20 cos (5 x + 7)

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

in v erse \frac{1}{2} (x - 3)^{2} + 3

in v erse y = \frac{x ^{3}}{8} - 1
