How to solve for interval
WebIf you have a x^2 term, you need to realize it is a quadratic function. There is no meaning to increasing and decreasing because it is a parabola (sort of a U shape) unless you are … WebFirst, let us clear out the "/3" by multiplying each part by 3. Because we are multiplying by a positive number, the inequalities don't change: −6 < 6−2x < 12. Now subtract 6 from each part: −12 < −2x < 6. Now divide each part by 2 (a positive number, so again the inequalities don't change): −6 < −x < 3.

WebSolve Compound Inequalities in the Form of “ or”. As we saw in the last section, the solution of a compound inequality that consists of two inequalities joined with the word or is the union of the solutions of each inequality. Unions allow us to create a new set from two that may or may not have elements in common. WebLet's find the intervals where f (x)=x^3+3x^2-9x+7 f (x) = x3 +3x2 −9x +7 is increasing or decreasing. First, we differentiate f f: f' (x)=3x^2+6x-9 f ′(x) = 3x2 +6x−9 [Show entire calculation] Now we want to find the intervals where f' f ′ is positive or negative. f' (x)=3 …

WebJul 5, 2024 · You need to show that for every r > 0 there exists a d > 0 such that x-y < d => f (x) - f (y) < r. Example, let f (x) = x. Then for any r > 0 pick r = d then x - y < d = r => f (x) - f (y) = x - y < r. Example, let f (x) = x^2. Then for any r > 0 observe that x^2-y^2 = x-y * x+y . So if …
