if x < 10
f(x) =

is continous at x=10, the value
if x > 10
Is the function f(x) given
of a is:
below ,continuous at x=2?
O a=4
1.5
a=10
0.5
a=-20
1
-0.5
O a=1
O a. The left and the right
limits at x=2 are same.
but f(x) at x = 2 is
different.So the
function is not
continuous at x=2
O b. The left and the right
- 32
lim,-2 (-
x – 2
limits at x=2 are same.
but f(x) at x = 2 does
not exist.So the
function is not
72
continuous at x=2
60
O c. The left and the right
limits and the value of
f(x) at x=2 are not
same.So the function is
O 80
o none
not continuous at x=2
O d. The left and the right
limits at x=2 are
same.So the function is
continuous at x=2
O O
