Question 203520: Given the function t(x)=-sqrt(x+2)+1, find the inverse [t-1(x)].
I've gotten as far as y=-x^2+3. I don't know if this is correct, I don't know how to figure out if it is. I'm particularly perplexed about how I deal with the negative sign in front of the sqrt in the original problem.
These inverse problems are just mystifying - I don't get it. Please help me by showing me how you solve the problem.
Thanks so much!
