Find f^(-1)for the function f(x)= (1)/(x+2)

Artyom0805 [142]

If $f(x)$ and $f^{-1}(x)$ are inverses of each other, then we have

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

Since $f(x) = \frac1{x+2}$ , we have

$f\left(f^{-1}(x)\right) = \dfrac1{f^{-1}(x)+2} = x$

Solve for $f^{-1}(x)$ :

$\dfrac1{f^{-1}(x)+2} = x \\\\ 1 = x\left(f^{-1}(x)+2\right) \\\\ 1 = x f^{-1}(x) + 2x \\\\ x f^{-1}(x) = 1 - 2x \\\\ f^{-1}(x) = \dfrac{1-2x}x \\\\ \boxed{f^{-1}(x) = \dfrac1x - 2}$

(provided that <em>x</em> ≠ 0 and <em>x</em> ≠ -2)

Campbell’s paycheck was $257.29. She put 1/4 of her paycheck into a savings account and used 1/3 of what was left to pay bills.

Stells [14]

Answer:

She has $128.65 left

Step-by-step explanation:

$257.29 x 1/4 = $64.32

$257.29 - $64.32 = $192.97

$192.97 x 1/3 = $64.32

$192.97 - $64.32 = $128.65

Find the value of x. Round to the nearest tenth <br> PLEASE HELP

ololo11 [35]

Answer:

x = 38.2°

Step-by-step explanation:

<u> sin 27° </u> = <u> x° </u>

11 15

15 · (sin 27°) = 11 · x°

cross-multiply:

6.81 = 11x

6.81 / 11 = x

x = 0.619

sin^-1 (0.619) = 38.2°
