Student-specific | 2 solutions for a complex function evaluation domain


Prepare for college entrance examination mathematics, save strength every day

High school students mathematics master forging "1 day 1 road" action

Idea: Known function analytic and domain, the most common way to evaluate the domain is to combine function monotonicity. Since the function f(x) is not a well-known basic elementary function, monotonicity cannot be directly seen, so a derivation is required.

Keywords: value domain, monotonicity, parity, number and shape combination, variable substitution
