Question

I just need help on the solving part of this question... I understand the beginning, ill give a medal(:. Ill post it below.

Answer 1

If \[f(x)=\frac{ 1 }{ 2 }x-6\], what is the equation for \[f ^{-1}(x)\]

Answer 2

y = (1/2)x -6
x = (1/2)y-6
add 6 to both sides, what u get ?

Answer 3

x+6=1/2y

Answer 4

right, now multiply both sides by 2 ....

Answer 5

2(x+6)... should I distribute the 2 because theres an answer where it is distributed and an answer where its not

Answer 6

what do u get after distributing ?

Answer 7

oh wait there is 2(x+6) and 2x+6 so it would have to be 2(x+6) right?

Answer 8

yes,
after distributing
2x +12
so, 2 (x+6) wouk be correct :)

Answer 9

okay I understand thank you so much (:
