The function defined as f(x)= _ n [ array ll ^ 2 n x & If x 0 n 1+x^n & 0 x 1 1 1+x^n & x 1 array . which of the following does not hold good
Options
- Acontinuous at x=0 , but discontinuous at x=1
- Bcontinuous at x=1 , but discontinuous at x=0
- Ccontinuous at both x=1 and x=0
- Ddiscontinuous at both x=1 and x=0
Correct answer
C. continuous at both x=1 and x=0
Step-by-step solution
aligned & f (0⁻ )=0, f (0⁺ )=1, f (0)=1 & discontinuous at x =0 & f (1⁻ )=1, f (1)=1, f (1⁺ )=0 & discontinuous at x =1 aligned
