Answer:
w=-5
Step-by-step explanation:
3w=-18+3
3w=-15
w=-5
The inverse of the function f(x) = 2x - 10 is f-1(x) would be x/2 + 5.
Lets try to solve it,
We will be using the inverse function to solve this.
f(x) =
Replace f(x) with y.

Interchange x and y

Solve for y

Replace y with f-1(x).

Thus, the inverse of the function f(x) = 2x - 10 is f-1(x) = x/2 + 5
