inverse of f(x)=-2*3^{2x-1}+1/2

inverse

f (x) = - 2 \cdot 3^{2 x - 1} + \frac{1}{2}

\frac{ln ( - \frac{3 ( 2 x - 1 )}{4} )}{2 ln ( 3 )}

Solution steps

y = - 2 \cdot 3^{2 x - 1} + \frac{1}{2}

Replace

x

with

y

x = - 2 \cdot 3^{2 y - 1} + \frac{1}{2}

Solve for

y, x = - 2 \cdot 3^{2 y - 1} + \frac{1}{2}

\frac{ln ( - \frac{3 ( 2 x - 1 )}{4} )}{2 ln ( 3 )}
