If (x) and f'(x) are inverse functions of each other and S(x) = 2x+5, what is /?(8) ?
0 -1
0
41
8
0 23

the answer to this question is yes

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

95.03 is the answer. hope this !
