Answer:
Step-by-step explanation:
1. Replace F(x) with y.
2. Interchange x and y in y = 2x + 1: x = 2y + 1
3. Solve this result for y: 2y = x - 1, or y = (x - 1)/2
4. Replace y with:
-1
F (x):
-1 x - 1
F (x) = -----------

Answer:
f-1(x) = (x - 1)/2.
Step-by-step explanation:
Let f(x) = y
y = 2x + 1
2x = y - 1
x = (y - 1)/2
Now replace x by the inverse of f(x) ( that is f-1(x) ) and y by x:
f-1(x) = (x - 1)/2.
