Can interval notation have a fraction
WebWrite the solution in inequality notation or interval notation. If the quadratic inequality is in the form: (x – a) (x – b) ≥ 0, then a ≤ x ≤ b, and if it is in the form : (x – a) (x – b) ≤ 0, when a < b then a ≤ x or x ≥ b.

WebGraph on the number line: ⓐ x > − 2 ⓑ x < − 3 ⓒ x ≥ −1 We can also represent inequalities using interval notation. As we saw above, the inequality x > 3 means all numbers greater than 3. There is no upper end to the solution to this inequality. In interval notation, we express x > 3 as ( 3, ∞). The symbol ∞ is read as ‘infinity’.
WebHowever, this isn't necessary, since you can just change the expression inside the sum to get the same effect. So if you have the sum from i=1 to 10 of i², and you want to i to step by 1/3 instead of 1, you can change the expression i² to (1+(i-1)/3)², and have i … WebStep 1: Enter the inequality below which you want to simplify.
