f^{-1}(-8)=-4,f(-4)

f^{- 1} (- 8) = - 4, f (- 4)

f = 2

Solution steps

f^{- 1} (- 8) = - 4

Refine

- \frac{8}{f} = - 4

Multiply both sides by

f

- 8 = - 4 f

Switch sides

- 4 f = - 8

Divide both sides by

- 4

f = 2

Verify Solutions

Find undefined (singularity) points:

f = 0

Combine undefined points with solutions:

f = 2

0 = \frac{x}{x ^{2} - 4}

r, 0 = \frac{k q}{r ^{2}}

\frac{x ^{2}}{x - 6} + 3 = 0

(3 x)^{- 2} = 9

\frac{14}{y} = \frac{7}{2}
