Question

Find the inverse of f(x)= –9/x+8.

Answer 1

Do you want the answer or a step by step solution?

Answer 2

y = -9/x + 8
To find inverse, switch x and y. That is, replace x by y and y by x.
Express y as a function of x and that will be your inverse.

Answer 3

step by step solution

Answer 4

First set f(x) to Y.
You now have: y=-9/x+8

do you agree?

Answer 5

is it \[\frac{ -9 }{ x } + 8\] or \[\frac{ -9 }{ x+8 }\]

Answer 6

Hello?

Answer 7

\[\it is \frac{ -9 }{ x}+8\]

Answer 8

okay.
f(x) is the same as Y.
so now that we have y=-9/x+8, switch the x and y values.

Answer 9

okay

Answer 10

So do it

Answer 11

y=-9/y+8 ?

Answer 12

close! you have to change that y in the beginning, too. so: x=-9/y+8
now, try to solve for x.

the answer is f^-1(x) = -9/x-8 . I have to go, sorry
