inverse of f(x)=7^x

Solution

inverse

f (x) = 7^{x}

Solution

\frac{ln ( x )}{ln ( 7 )}

Solution steps

y = 7^{x}

Replace

x

with

y

x = 7^{y}

Solve for

y, x = 7^{y}

\frac{ln ( x )}{ln ( 7 )}

Popular Examples

inverse of 1/8 x^3 inverse

\frac{1}{8} x^{3}

intercepts of f(x)=(x^2-16)(x^3+8)^3 intercepts

f (x) = (x^{2} - 16) (x^{3} + 8)^{3}

domain of f(x)=2x-7 domain

f (x) = 2 x - 7

extreme f(x)=x^3-6x^2+16 extreme points

f (x) = x^{3} - 6 x^{2} + 16

inverse of f(x)= 2/3 x^3+1 inverse

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