Answer:
2.5
Step-by-step explanation:
it's the midpoint of XZ
The inverse function for the given function f(x) = 4x - 2 is x/4 + 2
or, f⁻¹(x) = x/4 + 2
Given function, f(x) = 4x-8
We have to find f⁻¹(x)
f(x) = 4x - 8
or, y = 4x - 8
Interchanging the x variable with y,
x = 4y - 8
Solving y,
x = 4(y - 2)
or, x/4 = y - 2
or, y = x/4 + 2
Now, replacing y with f⁻¹(x), we get;
f⁻¹(x) = x/4 + 2
For verifying, you can use
(f · f⁻¹ )(x) = x
Therefore, the inverse function of f(x) is x/4 + 2.

Answer:
Y = -2/3X + 8
Step-by-step explanation:
move X to other side with subtraction
3Y = -2X +8
get Y alone by dividing both sides by three
Y = -2/3X + 8
