from chapter 12
OpenStudy (immanuelv):
f^-1 (x) = (x-4 )/ (3)
OpenStudy (anonymous):
\[f \left( x \right)=3x+4\]

look at it like y=mx+b
or
y=3x+4
OpenStudy (anonymous):
i kno...but like can you hlep me find the Points i can Use to graph
OpenStudy (anonymous):
put your pincle on the y intercept of 4 move up 3 boxes and to the right 1
OpenStudy (anonymous):
its a chapter 12 problem i need to graph tht and the inverse
OpenStudy (immanuelv):
i told u the inverse

i kno....but i need to get the Normal graph Correct....
OpenStudy (immanuelv):
it is \[1±(\sqrt(3-x))/(\sqrt(2))\]
OpenStudy (anonymous):
is the square root on the 3 only???
OpenStudy (immanuelv):
it is the answer for f(x)= -2(x+1)^2 +3
OpenStudy (immanuelv):
and the square root is for the whole thing!

can you tell me the Point i would be using if i used 2, 1, 0, -1, -2
OpenStudy (anonymous):
and those numbers were x
OpenStudy (immanuelv):
??
OpenStudy (anonymous):
like in the Equation you gave me
OpenStudy (anonymous):
but put those numbers one by one for X and whats the answer everytime

OpenStudy (immanuelv):
for the equation i gave you?
OpenStudy (anonymous):
yea...the inverse
OpenStudy (anonymous):
for thise 1±((√3−x))/((√2))
OpenStudy (anonymous):
can you tell me what the answer is if you plug the 5numbers i told you
OpenStudy (immanuelv):
2= 1.707 and .2928
1= 2 and 0
0= 2.225 and -.2247
-1= 2.414 and -.414
-2 = 2.581 and -.581

is that helpful?
OpenStudy (immanuelv):
its 64
OpenStudy (anonymous):
huh?
OpenStudy (immanuelv):
sorry wrong post!
OpenStudy (anonymous):
whats the inverse of 4^x

(log x)/ (log 4)
OpenStudy (anonymous):
no its f(x)=4^x...i need inverse of that
OpenStudy (immanuelv):
it is its inverse!
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
\[f(x) = 4^x\]\[f(f^{-1}(x)) = x\implies x = 4^{f^{-1}(x)} \]\[\implies ln\ x = f^{-1}(x)( ln\ 4) \]\[\implies f^{-1}(x) = {ln\ x \over ln\ 4}\]
