inverse of ((x+7))/(sqrt(x))

inverse

\frac{( x + 7 )}{x}

\frac{- 14 + x ^{2} + x x ^{2} - 28}{2}, \frac{- 14 + x ^{2} - x x ^{2} - 28}{2}

Solution steps

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

Replace

x

with

y

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

Solve for

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

\frac{- 14 + x ^{2} + x x ^{2} - 28}{2}, \frac{- 14 + x ^{2} - x x ^{2} - 28}{2}

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

f (x) = \frac{1}{x ^{2} - 6 x + 11}

- 10 cos (\frac{π x}{6})

\frac{4 + x}{1 - 4 x}

\frac{x ^{3}}{x ^{2} - 1}
