Hello. I dont know what to say.
Hi
First Of All I'm Allen forget the John. K? \/^.^\/
Well today... nevermind.. yesterday we study about.. oh yea it's today
we study about Inversions. its easy like EZZZZZ
lets say you have
in this picture the points of the original functions are
(-2,4)
(-1,1)
(0,0)
(1,1)
(2,4)
all you have to do to get the inverse function is to switch the x-values and the y-values
which will give us
(4,-2)
(1,-1)
(0,0)
(1,1)
(2,4)
orrrrrr in this case
y=3x+2
to get the inverse function we need to switch x and y so it will be...
x=3y+2
andd thennn we need to isolate the y variable
x-2=3y
x-2/3=y
so the inverse function will be
y=1/3x-2/3 or y=x-2 over 3

OH! I passed my test <3 I hope guys do too.
