It's IB Precalculus, don't answer it if you haven't taken Precalc yet 😂

somnium · Answer

shush i can do math even if i havent learned it yet, ik my capabilities, i just dont remember them

0bviouslyNotRakita · Answer

g-1(x)= 1/2x-1
I think this is the correct answer

somnium · Answer

if it's just interchanging variables and simplifying like i remember, then it should be like this $$g ^{-1}(x)=2x-4$$

I believe that the answer was g^(-1)(x)=(1/2)x, how'd you get the -1 at the end of your equation?

Aratox · Answer

At least, I got my g^(-1)(x)=(1/2)x, I don't have the correct answer...

By dividing the -2 to the positive 2. Thats how I got -1
