How to solve an inequality analytically
WebMay 6, 2015 · estimate e − x 2 x 2 against some other function which is manageable. For example I know that e − x 2 x 2 < 1 / x 2 and 1 / x 2 < 1 for all x > 1. So x > 1 gives me a lower bound for x. try some value and use the fact that e − x 2 x 2 is strictly decreasing. So I find that x = 0.8 solves the inequality which gives me the slightly improved ...

WebJan 6, 2024 · Solve the following inequalities analytically using sign diagrams. Verify your answer graphically. 2x2 ≤ 3 − x x2 − 2x > 1 2x − x2 ≥ x − 1 − 1 Solution To solve 2x2 ≤ 3 − x, we first get 0 on one side of the inequality which yields 2x2 + x − 3 ≤ 0. We find the zeros of f(x) = 2x2 + x − 3 by solving 2x2 + x − 3 = 0 for x. Web2 days ago · Show Notes.
