inverse of ((x-1)^2)/(81)

inverse

\frac{( x - 1 ) ^{2}}{81}

9 x + 1, - 9 x + 1

Solution steps

y = \frac{( x - 1 ) ^{2}}{81}

Replace

x

with

y

x = \frac{( y - 1 ) ^{2}}{81}

Solve for

y, x = \frac{( y - 1 ) ^{2}}{81}

9 x + 1, - 9 x + 1

\frac{4}{9 + x}

f (x) = \frac{- 3 x + 7}{2 x + 6}

f (x) = \frac{2}{3} x + 10

f (x) = \frac{1}{2} 2 x + 1
