\[f \left( x \right)=3x+4\]
anonymous
  • anonymous
how will i graph that
anonymous
  • anonymous
look at it like y=mx+b or y=3x+4
anonymous
  • anonymous
i kno...but like can you hlep me find the Points i can Use to graph
anonymous
  • anonymous
put your pincle on the y intercept of 4 move up 3 boxes and to the right 1
anonymous
  • anonymous
its a chapter 12 problem i need to graph tht and the inverse
immanuelv
  • immanuelv
i told u the inverse
anonymous
  • anonymous
i kno....but i need to get the Normal graph Correct....
immanuelv
  • immanuelv
it is \[1±(\sqrt(3-x))/(\sqrt(2))\]
anonymous
  • anonymous
is the square root on the 3 only???
immanuelv
  • immanuelv
it is the answer for f(x)= -2(x+1)^2 +3
immanuelv
  • immanuelv
and the square root is for the whole thing!
anonymous
  • anonymous
ok
immanuelv
  • immanuelv
square root of 3-x
anonymous
  • anonymous
kk
immanuelv
  • immanuelv
:)
immanuelv
  • immanuelv
hope it helped!
anonymous
  • anonymous
it did but i need to show my work...its a damn Test
immanuelv
  • immanuelv
switch x and the y then solve for y again
anonymous
  • anonymous
lol
anonymous
  • anonymous
can you help me with my whole test???
immanuelv
  • immanuelv
for 5 min... gotta sleep!
immanuelv
  • immanuelv

anonymous
  • anonymous
ohhhh.....well im doin a Take home test rite now
immanuelv
  • immanuelv
k
anonymous
  • anonymous
can you tell me the Point i would be using if i used 2, 1, 0, -1, -2
anonymous
  • anonymous
and those numbers were x
immanuelv
  • immanuelv
??
anonymous
  • anonymous
like in the Equation you gave me
anonymous
  • anonymous
but put those numbers one by one for X and whats the answer everytime
immanuelv
  • immanuelv
for the equation i gave you?
anonymous
  • anonymous
yea...the inverse
anonymous
  • anonymous
for thise 1±((√3−x))/((√2))
anonymous
  • anonymous
can you tell me what the answer is if you plug the 5numbers i told you
immanuelv
  • 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
immanuelv
  • immanuelv
is that helpful?
immanuelv
  • immanuelv
its 64
anonymous
  • anonymous
huh?
immanuelv
  • immanuelv
sorry wrong post!
anonymous
  • anonymous
whats the inverse of 4^x
immanuelv
  • immanuelv
(log x)/ (log 4)
anonymous
  • anonymous
no its f(x)=4^x...i need inverse of that
immanuelv
  • immanuelv
it is its inverse!
anonymous
  • anonymous
ok
anonymous
  • anonymous
\[f(x) = 4^x\]\[f(f^{-1}(x)) = x\implies x = 4^{f^{-1}(x)} \]\[\implies ln\ x = f^{-1}(x)( ln\ 4) \]\[\implies f^{-1}(x) = {ln\ x \over ln\ 4}\]

  • immanuelv
i was right :)
