inverse of 2^{2-x}

Solution

inverse

2^{2 - x}

Solution

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

Solution steps

y = 2^{2 - x}

Replace

x

with

y

x = 2^{2 - y}

Solve for

y, x = 2^{2 - y}

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

h (x) = 2 x + 1, x \geq 0

inverse of y=-1/2 x+4/5 inverse

y = - \frac{1}{2} x + \frac{4}{5}

inverse of f(x)=(x+9)/5 inverse

f (x) = \frac{x + 9}{5}

inverse of f(x)=e-9.304 inverse

f (x) = e - 9.304

inverse of f(x)=(y-1)/y inverse

f (x) = \frac{y - 1}{y}
