Answer:
D
Step-by-step explanation:
Given that
f(x)=-2x – 1
g(x) = -1/2x+1/2
I The function f( g(x)) = x for all real x.
-2(-1/2X + 1/2) - 1
X - 1 - 1
X - 2
II. The function glAx)) = x for all real x.
- 1/2( -2X - 1 ) + 1/2
X + 1/2 + 1/2
X + 1
III. Functions fand g are inverse functions
Inverse of f(x)
Y = -2x - 1
X = - 2Y - 1
- 2Y = X + 1
Y = - 1/2X - 1/2
Therefore, none of the above answers is correct.
The correct answer is therefore D

------------------------
Let x = number of miles, cost per mile = 93 cents = $0.93
Cost = 20.95 + 0.93*x
200.44 = 20.95 + 0.93x
0.93x + 20.95 = 200.44
0.93x = 200.44 - 20.95
0.93x = 179.49
x = 179.49/0.93
x = 193
He drove 193 miles.
