Given f(x) = the quantity of x minus 1, divided by 2, solve for f−1(5). 2 9 11 15

bearhunter [10]

F ( x ) = ( x - 1 ) / 2
y = ( x - 1 ) / 2
x - 1 = 2 y
x = 2 y + 1
f ^(-1) ( x ) = 2 x + 1 ( this is inverse function )
f ^(-1) ( 5 ) = 2 * 5 + 1 = 10 + 1 = 11

Answer: $ln(x^{\frac{1}{4}}y^{\frac{1}{2}}z^{\frac{2}{3}})$

Step-by-step explanation:

Formula:

$k\times ln(a)=ln(a^{k})$

$ln(a)+ln(b)=ln(ab)$

$ln(a)-ln(b)=ln(\frac{a}{b})$

$\frac{1}{4}\times ln(x)=ln(x^{\frac{1}{4}})$

$\frac{-1}{2}\times ln(x)=ln(x^{\frac{-1}{2}})$

$\frac{2}{3}\times ln(x)=ln(x^{\frac{2}{3}})$

Working:

So, $\frac{1}{4}ln(x)-\frac{1}{2}ln(y)+\frac{2}{3}ln(z)=ln(x^\frac{1}{4})-ln(y^\frac{-1}{2})+ln(z^\frac{2}{3})$

= $ln(\frac{x^\frac{1}{4}}{y^{\frac{-1}{2}} } )+ln(z^{\frac{2}{3}})$

= $ln(x^\frac{1}{4}}{y^{\frac{1}{2}}z^{\frac{2}{3} })$
