In order to integrate a function involving absolute value, we first must determine where the function inside the absolute value is positive or negative. Then we split the integral into two separate integrals based on that information.Answer and Explanation: We first determine when 2x...

The absolute value of a number is equal to the distance between that number and zero on the number line. Since absolute value is a distance, it is always positive, or equal to zero. The absolute value of a numberxis denoted by|x|. Ifxis positive or zero, then|x|=xand ifxis negati...
Hi guys, I have a little problem with this question: Determine the limit (x approaching infinity) \frac{|9-3x^{2}|}{x-2x^{2}} (Sorry, I'm not sure on how to use the Latex feature) Anyways, I've combed the forum and found a couple of threads that are somewhat related to my...
Solution: The absolute value of -3 is 3 (since we need to change the sign to make it positive), and the absolute value of 7 is 7. Thus, |-3| + |7| = 3 + 7 = 10. Solve the equation |2x – 5| = 9. Solution: The equation |2x – 5| = 9 means that the distance betwee...
