No. The function is not continuous at x=1.
OpenStudy (anonymous):
can you explain to me why it isn't?
OpenStudy (anonymous):
Well, substitute x=1 in the equation. The value of x becomes infinite. Hence the value isn't defined at that point... x=0.99 and x=1.01( the neighbourhood of 1), the function has a finite value but not for x=1
