IB DP Maths: AA HL复习笔记2.8.2 Polynomial Inequalities
How do I solve polynomial inequalities? STEP 1: Rearrange the inequality so that one of the sides is equal to zero For example: P(x) ≤ 0 STEP 2: Find the roots of the polynomial You can do this by ...
IB DP Maths: AA HL复习笔记2.8.1 Solving Inequalities Graphically
How can I solve inequalities graphically? Consider the inequality f(x) ≤ g(x), where f(x) and g(x) are functions of x if we move g(x) to the LHS we get f(x) – g(x) ≤ 0 Solve f(x) – g(x) = 0 to find...
