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)

Please help me by marking me brainliest. I'm really close :)
It is difficult because prime numbers are numbers with no factors. There's not many. A lot of one digit numbers are prime and odd numbers but after 2, all of the even whole numbers are composite and some odds past 100 (and some before 100) are, also
