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.

Which phrase is NOT a way to state the meaning of the expression y - 77
Vera_Pavlovna [14]

Hey there!

(I believe your answer choices meant to say ‘77’, not ‘7’)

I think the correct answer is A. 77 less than a number

Hope this helps you!

God bless ❤️
