Ex 5.1, 3 Examine the following functions for continuity. (a) f(x) = x β 5 f(x) = x β 5 To check continuity of π(π₯), We check itβs if it is continuous at any point x = c Let c be any real number f is continuous at π₯ =π if (π₯π’π¦)β¬(π±βπ) π(π)=π(π) (πππ)β¬(π±βπ) π(π) = limβ¬(xβπ) π₯ β 5 = c β 5 π(π) = c β 5 Since, L.H.S = R.H.S β΄ Function is continuous at x = c Thus, we can write that f is continuous for x = c , where c βπ β΄ f is continuous for every real number.
