WebCASE 1: CASE 2: CASE 3: The absolute value of any number is either zero (0) (0) or positive which can never be less than or equal to a negative number. The answer to this case is always no solution. CASE 4: The absolute value of any number is either zero (0) (0) or positive. It makes sense that it must always be greater than any negative number ... WebIf an inequality has no real solution, this means that there are no numbers that can be substituted into the inequality to make the statement true. If an inequality has all real...

WebApr 4, 2024 · Definition 8.3. An infinite series of real numbers is the sum of the entries in an infinite sequence of real numbers. In other words, an infinite series is sum of the form. a1 + a2 + · · · + an + · · · = ∞ ∑ k = 1ak, where a1, a2,..., are real numbers. We will normally use summation notation to identify a series. WebBecause you can't take the square root of a negative number, sqrt (x) doesn't exist when x<0. Since the function does not exist for that region, it cannot be continuous. In this video, we're looking at whether functions are continuous across all real numbers, which is why sqrt (x) is described simply as "not continuous;" the region we're ...
