求反函数 3(2^{4x-5})

解答

求反函数

3 (2^{4 x - 5})

\frac{ln ( \frac{32 x}{3} )}{4 ln ( 2 )}

求解步骤

y = 3 \cdot 2^{4 x - 5}

用

y

替代

x

x = 3 \cdot 2^{4 y - 5}

求解

y, x = 3 2^{4 y - 5}

\frac{ln ( \frac{32 x}{3} )}{4 ln ( 2 )}

in v erse lo g_{2} (3 x + 4) - 5

in v erse h (x) = \frac{7 x}{x - 4}

in v erse f (x) = - \frac{( 3 x + 18 )}{5}

in v erse f (x) = 2 - x^{2}, 3 \leq x \leq 2

in v erse f (x) = 3 - 29 x
