Question

if f(x) and g(x) are one-to-one functions such that f(5)=3 and g^-1(6)=-8.
find f^-1(3)-g(-8)

Answer 1

g^-1 ( 6)= -8 ---> g( -8 ) = 6
f ( 5 ) = 3 ---> f^-1 (3) = 5
---> answer: 5 - 6 = -1

Answer 2

wow was it that easy?... thank you very much :D

Answer 3

:)

Answer 4

How would you transform the graph of y= f (x ) to obtain the graph of
y= -3f (x 2) 5 ? If (7, -3) is a point on the graph of y= f (x ) , what would be
the corresponding point on the graph of y=-3f (x 2) 5 ?
