inverse of f(x)=((x^{(2)}-2))/((2x+1))

inverse

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

x + x^{2} + x + 2, x - x^{2} + x + 2

Solution steps

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

Replace

x

with

y

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

Solve for

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

x + x^{2} + x + 2, x - x^{2} + x + 2
