Hint - Let f(x) = 3^x - x^2 1. f(x) is continous 2. what is f(-1) and f(0) Cna you take it from here?
Lovely! krtica, aman_cc's point is that you are NOT asked to find such an x, just prove that it exists.
It is against the rules to remove the OP. See Rule # 7. If you don't restore the original question, a mod will do that for you and you'll get an infraction. You've been warned.
