If f^-1(x) is the inverse of f(x), which statement must be true?

k0ka [10]

F(f-1x) will be equal to x

take a simple example

f(x) = 2x

so x = f(x) / 2

f-1(x) = x/2

f(f-1x) = 2 ( x/2) = 2 * x/2 = x

Which explains how to find the quotient of the division below? Negative 3 and one-third divided by StartFraction 4 over 9 EndFra

Ulleksa [173]

Answer:

(B) Write Negative 3 and one-third as Negative StartFraction 10 over 3 EndFraction, and find the reciprocal of StartFraction 4 over 9 EndFraction as StartFraction 9 over 4 EndFraction. Then, rewrite Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction as Negative StartFraction 10 over 3 EndFraction times StartFraction 9 over 4 EndFraction. The quotient is Negative 7 and StartFraction 6 over 12 EndFraction = Negative 7 and one-half.

Step-by-step explanation:

To find the quotient of the division:

$-3\dfrac13 \div \dfrac49$

Step 1: $\text{Write}$ $ -3\dfrac13$ as $ -\dfrac{10}{3}$

$-3\dfrac13 \div \dfrac49 = -\dfrac{10}{3} \div \dfrac49$

Step 2: Find the reciprocal of $\dfrac94$

$-\dfrac{10}{3} \times \dfrac94\\=-7\dfrac12$
