Hello!</h2>
The answer is:
The first option,

<h2>
Why?</h2>
To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".
We are given the function:

Write "f(x)" is equal to write "y", so:

Now, finding the inverse, we have:

Hence, we have that the answer is the first option,

Have a nice day!
Answer:
One solution
Step-by-step explanation:
Move variables to one side and constants to the other.
x-4y=-1
2x+8y=8 Divide this by 2
x+4y=4
Add the equations
2x=-3
x=-1.5
y=-1/8
Answer:
Option
