Final answer:

The function f(x) = (x+3)/5 has an inverse function f^(-1)(x) = 5x - 3.

Step-by-step explanation:

The function f(x) = (x+3)/5 has an inverse function.

To find the inverse function, we can follow these steps:

  1. Replace f(x) with y: y = (x+3)/5
  2. Swap x and y: x = (y+3)/5
  3. Solve for y: 5x = y + 3 --> y = 5x - 3

So, the inverse function is f^(-1)(x) = 5x - 3.

After extensive cheating found the answer is B F(x)=x^5-3

Anything anyone else says is wrong this got me 5/5
