...then solve for y,and change it to .
the domain of the inverse is equal to the range of f.
i cant seem to get the inverse of this function. (oh and sorry if this is in the wrong place i didnt know where to put it)
f(x)=1-2^x x E R
ive got so far but i cant seem to finish it .... and how do you find the domain of this invserse (is it x E R)
