inverse of f(x)=(x-7)/(x+1)

Solution

inverse

f (x) = \frac{x - 7}{x + 1}

Solution

\frac{- 7 - x}{x - 1}

Solution steps

y = \frac{x - 7}{x + 1}

Replace

x

with

y

x = \frac{y - 7}{y + 1}

Solve for

y, x = \frac{y - 7}{y + 1}

\frac{- 7 - x}{x - 1}

Popular Examples

range of f(x)=((8x-3))/x range

f (x) = \frac{( 8 x - 3 )}{x}

domain of f(x)= x/(sqrt(25-x^2))domain

f (x) = \frac{x}{25 - x ^{2}}

f (x) = x^{2}

f(x)=sqrt(x^2-4)

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

domain of f(x)= 1/(x^2-x-6)domain

f (x) = \frac{1}{x ^{2} - x - 6}
