Solving for x with absolute value
WebWhich says the absolute value of x equals: x when x is greater than zero; 0 when x equals 0; −x when x is less than zero ... Example: Solve x < 3. This means the distance from x to zero must be less than 3: Everything in between (but not including) −3 and 3.

More … About Ads - Absolute Value in Algebra - Math is Fun −6 < −x < 3. Now multiply each part by −1. Because we are multiplying by a negative … Interval Notation. In "Interval Notation" we just write the beginning and ending … WebThis equation can be thought of as the sum of two functions, if you replace y with f(x). The slope, when x is less than 1.5, is equal to 0, and f(0)=9. For x>1.5, the slope is 2, so f(x)=>9 for all x. I think the book meant "Is there an x-intercept to the function?, If so, find it."
