The function is
and the interval is
.
Construct a table for different values of
in the interval
.
![]() | \

Observe the table:
\The value of
do not change the sign for
in the interval
.
And there is no sign change between
and
.
As the
tends to
from the left
decreases, then begins increasing at
.
By the location principle, there may be real zeros between consecutive integers
and
.
Graph of the function
:
Observe the graph:
\The curve does not crosses the
-axis. between
and
.
Therefore, there are no zeros of
on
.
There are no zeros of
