👉 A term that describes a mathematical concept where a function is not defined at a particular point, or in a region where the limit does not exist. This means that for any value of x, there exists no corresponding y-value for which the function f(x) = g(x) is defined. For example, consider the function: f(x) = 2x^3 - 4x + 1 This function has a singularity at x=0 because the limit as x approaches
