f^{-1}(3)=1

f^{- 1} (3) = 1

f = 3

Solution steps

f^{- 1} (3) = 1

Refine

\frac{3}{f} = 1

Multiply both sides by

f

3 = f

Switch sides

f = 3

Verify Solutions

Find undefined (singularity) points:

f = 0

Combine undefined points with solutions:

f = 3

x^{2} + \frac{1}{x ^{2}} = 7

4 = \frac{8.4}{x}

2 - \frac{4}{x} = \frac{1}{3}

\frac{5}{3} = \frac{4}{x} - 1

\frac{2}{4} = \frac{8}{x}
