Example 5 Check the points where the constant function π (π₯) = π is continuous. Given π(π₯)=π (where π is any constant) 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) (π₯π’π¦)β¬(π±βπ) π(π) "= " limβ¬(xβπ) " " π = π π(π) = π 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.
