inverse of 1-x-x^2

Solution

inverse

1 - x - x^{2}

Solution

- \frac{1 + - 4 x + 5}{2}, - \frac{1 - - 4 x + 5}{2}

Solution steps

y = 1 - x - x^{2}

Replace

x

with

y

x = 1 - y - y^{2}

Solve for

y, x = 1 - y - y^{2}

- \frac{1 + - 4 x + 5}{2}, - \frac{1 - - 4 x + 5}{2}

Popular Examples

domain of h(x)=(19)/(x^2-3x)domain

h (x) = \frac{19}{x ^{2} - 3 x}

inflection 9/x inflection points

\frac{9}{x}

domain of (x^3+4x^2)/(7x^2-2)domain

\frac{x ^{3} + 4 x ^{2}}{7 x ^{2} - 2}

parity f(x)=sin(-pit)parity

f (x) = sin (- π t)

asymptotes of f(x)= 5/(x^2+2x-3)asymptotes

f (x) = \frac{5}{x ^{2} + 2 x - 3}
