inverse of (x^2)/(x+1)

inverse

\frac{x ^{2}}{x + 1}

\frac{x + x ^{2} + 4 x}{2}, \frac{x - x ^{2} + 4 x}{2}

Solution steps

y = \frac{x ^{2}}{x + 1}

Replace

x

with

y

x = \frac{y ^{2}}{y + 1}

Solve for

y, x = \frac{y ^{2}}{y + 1}

\frac{x + x ^{2} + 4 x}{2}, \frac{x - x ^{2} + 4 x}{2}

2 x - 13

\frac{1}{x + 2} - 1

(2 x^{2} - 1) (- x^{2} - 6)

y = \frac{2 x - 4}{3 x + 5}

f (x) = \frac{9 x}{x + 2}
