WebProblem-Solving Strategy: Determining Continuity at a Point. Check to see if f (a) f ( a) is defined. If f (a) f ( a) is undefined, we need go no further. The function is not continuous at a a. If f (a) f ( a) is defined, continue to step 2. Compute lim x→af (x) lim x → a f ( x). WebJul 18, 2015 · Each of the 4 functions is continuous on the interval on which it is used: 3x − 1, x2 +1, and x − 4 are polynomials, hence continuous everywhere. 5 x − 2 is discontinuous at 2, but it is not used near 2, so that is not a problem. We need to check for continuity at the numbers 2, 7, and 9.
