Question

I really need the help please and thank you

Answer 1

Answer:

B.  $f^{-1}(x)=\frac{x-4}{5}$

Step-by-step explanation:

To find the inverse of a function/equation:

1. Replace f(x) with y: y=5x+4
2. Switch x and y: x=5y+4
3. Solve for y: x-4=5y   ->    $y=\frac{x-4}{5}$
4. Write in standard inverse notation: $f^{-1}(x)=\frac{x-4}{5}$

I hope this helps!!
