Let and
then which of the following is not conitnous ?
f(x)+g(x)
f(x)-g(x)
f(x)*g(x)
f(x)/g(x)
As we have learned
Properties of Continuous function -
If are two continuous functions at a point a of their common domain D.Then fg are continuous at a and if then
is also continuous at x = a.
-
qare continous foa all
and will be discontinous whenever g(x)=0 , so there are various x in such that g(x)= cos x=0
is not continous throughout
Option 1)
f(x)+g(x)
Option 2)
f(x)-g(x)
Option 3)
f(x)*g(x)
Option 4)
f(x)/g(x)
