inverse of f(x)=3^x-9

Solution

inverse

f (x) = 3^{x} - 9

Solution

\frac{ln ( x + 9 )}{ln ( 3 )}

Solution steps

y = 3^{x} - 9

Replace

x

with

y

x = 3^{y} - 9

Solve for

y, x = 3^{y} - 9

\frac{ln ( x + 9 )}{ln ( 3 )}

Popular Examples

parallel y=x-3,(3,-2)parallel

y = x - 3, (3, - 2)

range of f(x)=x^3-x range

f (x) = x^{3} - x

range of f(x)=sqrt(5-x)range

f (x) = 5 - x

intercepts of 5e^{-(x+1)^2}intercepts

5 e^{- (x + 1)^{2}}

intercepts of f(x)=x^4-9x^2 intercepts

f (x) = x^{4} - 9 x^{2}
