Question

emilyjones284 · Answer

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

hartnn · Answer

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

emilyjones284 · Answer

x+6=1/2y

hartnn · Answer

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

emilyjones284 · Answer

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

hartnn · Answer

what do u get after distributing ?

emilyjones284 · Answer

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

hartnn · Answer

after distributing 
2x +12
