Answer:
![f^{-1} = \frac{x-1}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%3D%20%5Cfrac%7Bx-1%7D%7B2%7D)
Step-by-step explanation:
![f(x) = 2x+1](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%2B1)
<em>Replace it with y</em>
![y = 2x+1](https://tex.z-dn.net/?f=y%20%3D%202x%2B1)
<em>Exchange the values of x and y</em>
![x = 2y+1](https://tex.z-dn.net/?f=x%20%3D%202y%2B1)
<em>Solve for y</em>
![x = 2y+1](https://tex.z-dn.net/?f=x%20%3D%202y%2B1)
<em>Subtracting 1 from both sides</em>
![2y = x-1](https://tex.z-dn.net/?f=2y%20%3D%20x-1)
<em>Dividing both sides by 2</em>
![y = \frac{x-1}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7Bx-1%7D%7B2%7D)
<em>Replace it by </em>![f^{-1}](https://tex.z-dn.net/?f=f%5E%7B-1%7D)
So,
![f^{-1} = \frac{x-1}{2}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%3D%20%5Cfrac%7Bx-1%7D%7B2%7D)
12.072 is irrational because it cannot be simplified into a fraction or ratio.
Answer:
A
Step-by-step explanation:
![\frac{\sqrt{16} }{\sqrt{8} } = \sqrt{\frac{16}{8} } = \sqrt{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B16%7D%20%7D%7B%5Csqrt%7B8%7D%20%7D%20%20%3D%20%5Csqrt%7B%5Cfrac%7B16%7D%7B8%7D%20%7D%20%20%3D%20%5Csqrt%7B2%7D)
