simplify f^{-1}(-7)

Solution

simplify

f^{- 1} (- 7)

Solution

- \frac{7}{f}

Solution steps

f^{- 1} (- 7)

Apply exponent rule:

a^{- 1} = \frac{1}{a}

= (- 7) \frac{1}{f}

Remove parentheses:

(- a) = - a

= - \frac{1}{f} \cdot 7

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= - \frac{1 \cdot 7}{f}

Multiply the numbers:

1 \cdot 7 = 7

= - \frac{7}{f}
