Find the inverse: f(x)=x+5/3x-1<br><br> f^-1x=

babunello [35]

We have $f(x)=\dfrac{x+5}{3x-1}$ .

To find inverse function $f^{-1}(x)$ we substitute x with $f^{-1}(x)$ and vice-versa to get

$x=\dfrac{f^{-1}(x)+5}{3f^{-1}(x)-1}$

Now solve for $f^{-1}(x)$ . Note that I will use $j$ instead.

$x=\dfrac{j+5}{3j-1} \\x(3j-1)=j+5 \\3jx-x=j+5 \\3jx-x-j-5=0 \\3jx-j=x+5 \\j(3x-1)=x+5 \\j=\dfrac{x+5}{3x-1}$

So we find that $f(x)=f^{-1}$ .

Hope this helps.

We can't see the table but if every input or x has only one specific output or y then it is a function so if every different height has one number of stories then it's a function you can have it though to were say you have 18 feet and 17 feet and they are both 3 stories then it's still a function but if you have 18 feet thats 3 stories and 18 feet thats 4 stories then its not a function
