inverse of f(x)=1-sqrt(2+x)

Solution

inverse

f (x) = 1 - 2 + x

Solution

x^{2} - 2 x - 1

Solution steps

y = 1 - 2 + x

Replace

x

with

y

x = 1 - 2 + y

Solve for

y, x = 1 - 2 + y

x^{2} - 2 x - 1

Popular Examples

inverse of f(x)=5e^{x-2}+6 inverse

f (x) = 5 e^{x - 2} + 6

inverse of f(x)=(x+1/2)^2-9/4 inverse

f (x) = (x + \frac{1}{2})^{2} - \frac{9}{4}

inverse of f(x)= 1/(x^3-4)inverse

f (x) = \frac{1}{x ^{3} - 4}

inverse of f(x)=(x/3)^{-3/2}inverse

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

inverse of f(x)=(2^x)/(2^x-1)inverse

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