Put y = f(x) y = 1/3x-2 Solve for x
anonymous
  • anonymous
How do I do that
anonymous
  • anonymous
Isolate x on one side of the equation

Can u solve it for me please

Hey to find the inverse of functions you got to do 4 steps. 1. Substitute f(x) with y. 2. Reverse the x and y variables. 3. Solve for y. 4. Replace y with f^-1x
anonymous
  • anonymous
Ok
anonymous
  • anonymous
Can you do the first step?
anonymous
  • anonymous
Y=1/3x-3
anonymous
  • anonymous
Everything's good but you accidentally wrote the last number wrong :) it's 2 :). Now can you do the 2nd step? ;)
anonymous
  • anonymous
So i add 2 to the other side
anonymous
  • anonymous
That's a bit later, but don't forget the 2nd step says to Reverse the x and y variables. Since our function is now y=1/3x-2, we'd switch the x & y over, and it'd now be x=1/3y-2 :) Do you get it so far? :)
anonymous
  • anonymous
and yeah on the 3rd step you'd then add 2 to both sides, & multiply by 3 to both sides as you're solving for y.
anonymous
  • anonymous
Yeah . do now lol I forgot about that part tthat's whats been screwing my up
anonymous
  • anonymous
If you forget, just use this problem to help you and eventually you'll be fine :) Did you get the answer? :)
anonymous
  • anonymous
No I'm confused again likeep how can u divided 1/3
anonymous
  • anonymous
*like
anonymous
  • anonymous
oh okay :) well we got x+2=1/3y To eliminate the 1/3, if we multiply it by it's reciprocal (opposite) which is 3, the 1/3 & 3 will cancel out leaving the y by itself :) and then we'd multiply 3 to the other side as well :) did you get that? :)
anonymous
  • anonymous
you multiply instead to cancel out the fraction by it's opposite number :)

Ohh pellet . Feel stupid now ugh

its okay :) everyone makes mistakes so it's a good thing you know how to :) I myself just learned this 2 days ago :p I made mistakes at first but I got it afterward :)
anonymous
  • anonymous
Okeyyy thanks sooo much
anonymous
  • anonymous
no prob. :) hey by some chance do you take algebra 2 on flvs? o.O
anonymous
  • anonymous
No im tmaking it i. School some of it is eeasy but some of it is just plan out hard why
anonymous
  • anonymous
oh okay, no prob. :) I take Alg. 2 on flvs so was just wondering bc just learned this as well :) well best of luck but i g2g now so bye :)
anonymous
  • anonymous
