Question

6. If f(x) = k xa ,x>=2
3,x> 2 is continuous , then k is equal to
a) 3
b) 4
c) 34
d) 1​

Answer 1

Answer:

Step-by-step explanation:

x a. +. → f (x) exist and are equal but not equal to f (a). (iii) f (a) is not defined. ... (i) The function y = f (x) is said to be differentiable in an open interval (a, b) if ... 3. –1. 2. 1. (tan ). 1. = + d x dx x. 4. –1. 2. 1. (cot ). 1 d x dx x. −. = +. 5. –1. 2. 1 ... k = 1. Thus, f is continuous at x = 0 if k = 1. Example 2 Discuss the continuity of the
