Question

Let f(x) = 1/(x+3)

Answer 1

More practice... y = 1/x+3
x = 1/y+3
and then multiply both sides by (y+3)?

Answer 2

Answer 4

yes

Answer 5

So I get f^-1(x) = xy+3x?

Answer 6

no
isolate y
xy + 3x = 1 solve for y

Answer 7

Divide all the way through by x

Answer 8

no
subtract 3x to the other side
then divide through by x

Answer 9

y = 1/x - 3

Answer 10

correct

Answer 11

f^-1(x) = 1/x-3

Answer 12

(1/x) -3
and yes :)

Answer 13

thanks :) I get confused about the algebraic steps because I want to do one thing and you are suppose to do another

Answer 14

yeah lol it's confusing sometimes >,<
