1. If f(x) and g(x) are inverses of one another, which of the following must be true?
a) (f. f)(x)=x
b) (g. f)(x)=x
c) (f. f^-1)(x)=x
d) two of the above
e) all of the above

2. Given f(x) =1/x-1 and g(x) = squaroot log(2x)
Determine (f. g)(x) and (f divide by g)(x)
State domain of each new function.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
