<h3>高一上学期主要学习函数，所以大大小小的考试中离不开以函数为背景的题目，所以对一些较复杂且常出现的函数提前学习了解，有助于在解题时，快速得到解题思路与方法。<br></br></h3></br><h3> <h3>简析：利用函数的奇偶性与单调性，化简不等式，然后是一个简单的恒成立问题。</h3></br><h3> <h3>简析：虽然我们已经清楚f(x)为R上的增函数，解答题还是要先证明一下，单调性和奇偶性都研究清楚后，利用两个性质化简已知不等式，参变分离后再利用换元法消根式，解不等式。</h3></br><h3> <h3>简析：利用换元法，将复杂的函数表达式转化为熟悉的二次函数，讨论对称轴与区间的位置关系，得到函数在何处取得最小值。</h3></br><h3> <h3>简析：方程有解问题，在这里通过参变分离，将变量一方构造为新函数，新函数单调性容易判断，从而容易求出值域。</h3></br><h3> <p class="ql-block"><span style="color: rgb(237, 35, 8);">扫描二维码关注公众号！</span></p> <a
