inverse of f(x)=-x^2-5x+2

inverse

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

- \frac{5 + - 4 x + 33}{2}, - \frac{5 - - 4 x + 33}{2}

Solution steps

y = - x^{2} - 5 x + 2

Replace

x

with

y

x = - y^{2} - 5 y + 2

Solve for

y, x = - y^{2} - 5 y + 2

- \frac{5 + - 4 x + 33}{2}, - \frac{5 - - 4 x + 33}{2}

f (x) = (9 x - 2)^{3}

\frac{x - 5}{4 x + 7}

f (x) = \frac{2}{( 3 x )} - 4

\frac{D}{D x} x^{3} + x + 1

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