The decimal number is 0.9
Answer:
10x + 9
Step-by-step explanation:
If f(x) is an inverse of g(x),
when
f(x)=y
g(y)=x
aka
f(g(x))=x
g(f(x))=x
basically, the values should be swiched
example
f(x)=
(1,2)
(2,3)
(4,5)
then g(x)=
(2,1)
(3,2)
(5,4)
You have to move the -2/5 by the 11j to get k by its self
K=11j+-2/5
this is a function becuase it passes the verticle line test (no 2 points are above each other).
