Honestly NOT That Difficult For The LAST Problem [Korean CSAT 2026]

South Korean College Scholastic Ability Test (CSAT) is the test that South Korean high school seniors take in order to apply for the college.

This problem from CSAT 2026 (for students who start their college in 2026) is about continuous and increasing function f(x) which also has an inverse. Two complicated conditions about the inverse are given, and you must find out the exact graph of the inverse (and thus f(x)). Moreover, you have to play with another confusingly defined function g(m) given as the number of intersection points. This is the very last problem, testing your ultimate calculus skill. Can you crush it?
