One way is to solve for the inverse of the first function
remember, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with ![f^{-1} (x)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%20%28x%29)
A.
![f(x)=x/2+8\\y=x/2+8\\x=y/2+8\\x-8=y/2](https://tex.z-dn.net/?f=f%28x%29%3Dx%2F2%2B8%5C%5Cy%3Dx%2F2%2B8%5C%5Cx%3Dy%2F2%2B8%5C%5Cx-8%3Dy%2F2)
![2x-16=y](https://tex.z-dn.net/?f=2x-16%3Dy)
![f^{-1}=2x-16](https://tex.z-dn.net/?f=f%5E%7B-1%7D%3D2x-16)
nope, not A
<h3>What is the inverse function?</h3>
The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by ![{\displaystyle f^{-1}.}](https://tex.z-dn.net/?f=%7B%5Cdisplaystyle%20f%5E%7B-1%7D.%7D)
B.
![f(x)=3x^3+16\\y=3x^3+16x=3y^3+16\\x-16=3y^3\\(x-16)/3=y^3](https://tex.z-dn.net/?f=f%28x%29%3D3x%5E3%2B16%5C%5Cy%3D3x%5E3%2B16x%3D3y%5E3%2B16%5C%5Cx-16%3D3y%5E3%5C%5C%28x-16%29%2F3%3Dy%5E3)
![f^{-1}(x)=\sqrt[3]{((x-16)/3)}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7B%28%28x-16%29%2F3%29%7D)
nope, not the same
not B
C.
![f(x)=18/x-9\\y=18/x-9\\x=18/y-9\\x+9=18/y\\y(x+9)=18\\y=18/(x+9)\\f^{-1}(x)=18/(x+9)](https://tex.z-dn.net/?f=f%28x%29%3D18%2Fx-9%5C%5Cy%3D18%2Fx-9%5C%5Cx%3D18%2Fy-9%5C%5Cx%2B9%3D18%2Fy%5C%5Cy%28x%2B9%29%3D18%5C%5Cy%3D18%2F%28x%2B9%29%5C%5Cf%5E%7B-1%7D%28x%29%3D18%2F%28x%2B9%29)
The correct, answer is C.

question one
1, 2, 3, 4, 5, 6
question two
3/6 or 1/2
question three
3/6 or 1/2
question four
2/6 or 1/3
question five
4/6 or 2/3
you use the list from question one, and count how many fit the criteria and put that number over the total ( which is 6 in this case )
