(Section 1.5: Piecewise-Defined Functions; Limits and Continuity in Calculus) 1.5.11 PART G: CONTINUITY IN CALCULUS f is continuous at a , or x = a ± 1) fa () is defined, 2) lim x ± a fx exists, and 3) lim x ± a = . f is discontinuous at a ± f is not continuous at a . (Some sources require that f be defined “around” a .) Comments 1) ensures that there is literally a point at a . 2) constrains the behavior of f immediately around a . 3) then ensures safe passage through the point
