Question 768291: I need help with this and checking my work =)
Find the inverse function of: F(x)=3-2x
I changed the x's to y's to come up with x=3-2y, then add 2y on both sides to get x+2y=3, then subtract x from both sides, giving me 2y=3-x and then divide by 2 to get y=3-x divided 2. Is that right??

The way I learned the process, you don't swap the variables until the very last step. But, giving it due consideration, it really shouldn't make any difference. And, at least in the case of this problem, it doesn't.
\ =\ 3\ -\ 2x)
\ =\ \frac{3\ -\ x}{2})
