f^{-1}(-2)=9,f(-6)

f^{- 1} (- 2) = 9, f (- 6)

f = - \frac{2}{9}

Decimal Notation

f = - 0.22222 \dots

Solution steps

f^{- 1} (- 2) = 9

Refine

- \frac{2}{f} = 9

Multiply both sides by

f

- 2 = 9 f

Switch sides

9 f = - 2

Divide both sides by

9

f = - \frac{2}{9}

Verify Solutions

Find undefined (singularity) points:

f = 0

Combine undefined points with solutions:

f = - \frac{2}{9}

18 (1 0^{- 6}) = \frac{x ^{2}}{1 - x}

\frac{48}{8} = \frac{42}{x}

\frac{z}{3} + \frac{z}{z - 5} = 0

\frac{9}{x + 1} = \frac{6}{x + 2}

\frac{0.14 x}{( 1.4 + x )} = 0.09
