求反函数 f(x)=ln(5t)

解答

求反函数

f (x) = ln (5 t)

\frac{e ^{t}}{5}

求解步骤

x = ln (5 t)

用

x

替代

t

t = ln (5 x)

求解

x, t = ln (5 x)

\frac{e ^{t}}{5}

d o main f (x) = \frac{2 x}{x ^{2} - 25}

in t erce pt s f (x) = \frac{( 5 x + 2 )}{x}

d o main f (x) = \frac{12 x + 35}{x ^{2} + 7 x}

a sy m pt o t es (\frac{4}{10})^{x}

cr i t i c a l f (x) = 2 x^{3} - 96 x + 42
