## anonymous 5 years ago find the inverse function of f(x)= 5/x-2

1. anonymous

f inverse = (5/x) + 2

2. anonymous

how you did it?

3. anonymous

type y = 5/ x-2 then make x the subject of the formula

4. anonymous

where did you get Y=5, and the other. Can you do it step by step plz?

5. anonymous

is it $f(x)=\frac{5}{x}-2$ or $f(x)=\frac{5}{x-2}$ ?

6. anonymous

steps are 1) y = 5/(x-2) 2) y(x-2) = 5 3) x= (5/y)+2 4) change x to y and y to x making it y = (5/x) +2

7. anonymous

the last one you wrote

8. anonymous

i am confuse , between the second to the third step

9. anonymous

from second to third step you (x-2) = 5/y then x=(5/y) + 2
