Answer:
B
Step-by-step explanation:
So we have the function:
![f(x)=\frac{9}{5}x+32](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B9%7D%7B5%7Dx%2B32)
To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:
![x=\frac{9}{5}f^{-1}(x)+32](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B9%7D%7B5%7Df%5E%7B-1%7D%28x%29%2B32)
Subtract 32 from both sides:
![x-32=\frac{9}{5}f^{-1}(x)](https://tex.z-dn.net/?f=x-32%3D%5Cfrac%7B9%7D%7B5%7Df%5E%7B-1%7D%28x%29)
Multiply both sides by 5/9. The right side will cancel. Thus:
![f^{-1}(x)=\frac{5}{9}(x-32)](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cfrac%7B5%7D%7B9%7D%28x-32%29)
Our answer is B.

I mean, there is no decimal place, so you can’t determine to the nearest hundredth place.
For the hundreds place, it would round to 100, though.
Answer:
20 the answer is 20 because you plug in 4 for n.
