SOLUTION: find f^-1(x) f(x)=e^x-3+2 i know that by putting the negitive on in it will make the neg. in the equation postive and i also know that positive will become neg. but i dont kno

Question 325244: find f^-1(x)
f(x)=e^x-3+2
i know that by putting the negitive on in it will make the neg. in the equation postive and i also know that positive will become neg. but i dont know where to go from there

You've mixed up notation here. With

, you are finding the inverse of f(x). The best way to do this is to first replace f(x) with y to get . Next, swap x and y to get . Finally, solve for 'y' (I'll let you do this) to find the inverse

. Note: the inverse will contain the natural log.
