WebMay 19, 2015 · The function f (x) is continuous at point a if and only if the limit lim x→a f (x) exists and equals f (a). So to prove that a function is continuous first you have to calculate the limit lim x→−1 (x + 2x3)4 = ( −1 +( −1)3)4 = ( − 2)4 = 16 The limit exists, so now you have to calculate f ( − 1) and check if the value equals the limit Web2) Taking the limit from the righthand side of the function towards a specific point exists. 3) The limits from 1) and 2) are equal and equal the value of the original function at the specific point in question. In our case, 1) 2) 3) Because all of these conditions are met, the function is continuous at 0.
