How to determine a continuous function

WebFor the absolute value function it's defined as: y = x when x >= 0 y = -x when x < 0 So obviously the left hand limit is -1 (as x -> 0), the right hand limit is 1 (as x -> 0), therefore the limit at 0 does not exist! WebIn mathematics, a continuous function is a function that does not have discontinuities that means any unexpected changes in value. A function is continuous if we can ensure …
