inverse of x^2+11x

inverse

x^{2} + 11 x

\frac{- 11 + 121 + 4 x}{2}, \frac{- 11 - 121 + 4 x}{2}

Solution steps

y = x^{2} + 11 x

Replace

x

with

y

x = y^{2} + 11 y

Solve for

y, x = y^{2} + 11 y

\frac{- 11 + 121 + 4 x}{2}, \frac{- 11 - 121 + 4 x}{2}

tan (2 x - 5)

f (x) = \frac{5 x}{5 x + 15} - 3

\frac{x ^{2} - 6 x + 5}{x - 3}

y = \frac{2 x ^{2}}{x ^{2} - 9}

ln (\frac{1}{x + 7})
