neverrrrrmindddddd

anonymous · Answer

you  would have swap the variables and solve for y

hartnn · Answer

so, you did figure out all of them ?

anonymous · Answer

dont feel stupid :P

anonymous · Answer

a quick way would be to plug in a test number but then it could also be the danger that the test point will work but it wont be an inverse function
