inverse of f(x)= 1/2*8^{3x+9}-7

inverse

f (x) = \frac{1}{2} \cdot 8^{3 x + 9} - 7

\frac{ln ( \frac{x + 7}{67108864} )}{9 ln ( 2 )}

Solution steps

y = \frac{1}{2} \cdot 8^{3 x + 9} - 7

Replace

x

with

y

x = \frac{1}{2} \cdot 8^{3 y + 9} - 7

Solve for

y, x = \frac{1}{2} \cdot 8^{3 y + 9} - 7

\frac{ln ( \frac{x + 7}{67108864} )}{9 ln ( 2 )}
