inverse of f(x)=3^x

Solution

inverse

f (x) = 3^{x}

Solution

\frac{ln ( x )}{ln ( 3 )}

Solution steps

y = 3^{x}

Replace

x

with

y

x = 3^{y}

Solve for

y, x = 3^{y}

\frac{ln ( x )}{ln ( 3 )}

Popular Examples

parallel (-3.5)y=-4x+5 parallel

(- 3.5) y = - 4 x + 5

inverse of f(x)=5x+3 inverse

f (x) = 5 x + 3

critical (0.22x)/(x^2+4)critical points

\frac{0.22 x}{x ^{2} + 4}

perpendicular 5y=2x-4,(0,7)perpendicular

5 y = 2 x - 4, (0, 7)

domain of sqrt((-x+3)/(x^2-1))domain

\frac{- x + 3}{x ^{2} - 1}
