f:R-->R

f(x)=1 if

f(x)=0 otherwise.

(a) Is f continuous at the point a = 0?

(b) Is f continuous at the point a = 1?

have i done them correctly?

Continuous at a=0 because correct?

also continuous at a=1 because

thanks

I see what you mean. The function is not connected at zero and hence the limit in first case doesn't exist so not continuous at a=0
