👉 slackness in mathematics refers to a property of a function that measures how close it is to a line. A function is said to be slack if its slope at any point is greater than or equal to 1, which means that as x approaches b from the left (or right), f(x) approaches infinity or negative infinity, respectively. For example, consider the function f(x) = x^2 - 6x + 3. At x=0, f(0)=0
