Use f(x) = 1)2 and f^-1(x) = 2x to solve the problems. a) f(2) b)f^-1(1) c)f^-1(f(2))

Luden [163]

a) f (2) = 1

b) $f^{-1}(1)=2$

c) $f^{-1}(f(2))=2$

<u>Step-by-step explanation:</u>

$f^{-1}$ - Indicates that we have to find the inverse of the function

Given data:

$f(x)=\left(\frac{1}{2}\right) x$ --------> eq.1

$f^{-1}(x)=2 x$ ---------> eq.2

To find $f(2), f^{-1}(1), f^{-1}(f(2))$

Case a)

Now, substitute x = 2 in the equation 1 to find f (2)

$f(2)=\left(\frac{1}{2}\right) \times 2=1$

Case b)

Now, substitute x = 1 in the equation 2 to find $f^{-1}(1)$

$f^{-1}(1)=2(1)=2$

Case c)

In general,

$f^{-1}(f(x))=f\left(f^{-1}(x)\right)=x$

Thereby,

$f^{-1}(f(2))=2 \text { where } x=2$

a payday loan store charges $30 for a one-month loan of $600. What is the annual interest rate is this equivalent to ?

lana [24]

Finding what percentage is $30 of $600:
$\frac{30}{600} \times100=5\%$
So, it is 5% per month.

Converting it to annual:
$5\%\times 12=60\%$
