inverse of f(x)=2^{x+1}

Solution

inverse

f (x) = 2^{x + 1}

Solution

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

Solution steps

y = 2^{x + 1}

Replace

x

with

y

x = 2^{y + 1}

Solve for

y, x = 2^{y + 1}

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

(0, 5), (5, 0)

inflection f(x)=3x^4-4x^3+2 inflection points

f (x) = 3 x^{4} - 4 x^{3} + 2

inverse of f(x)=(-5+5x)/(2-3x)inverse

f (x) = \frac{- 5 + 5 x}{2 - 3 x}

extreme f(x)=x^3+3x^2-9x extreme points

f (x) = x^{3} + 3 x^{2} - 9 x

inverse of y=9log_{4}(x)inverse

y = 9 lo g_{4} (x)
