Explanation:
Detailed explanation-1: -This is a rational function, so it will be discontinuous at points where the denominator becomes zero. Hence the function f ( x ) = 4 − x 2 4 x − x 3 will be discontinuous at exactly three points 0, -2 and 2.
Detailed explanation-2: -Question: At what point is the function continuous? y= x +1 x2-4x +3 All except x=2 The function is continuous everywhere.
Detailed explanation-3: -∴ The points of discontinuities are 0, ±1 and their number is 3.
