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.

When you solve a square root problem, can you just divide it by 2? for example in this picture can you do 25 divided by 2?

user100 [1]

Answer:

Step-by-step explanation:

When you square a number, you chose a number and multiplying itself. If you did the square root of 25, you would get 5. However if you divided 25 by 2, you would get 12.5 which is NOT the square root.
