The function is
and the interval is

Construct a table for different values of
in the interval
.

Observe the table:
\
is negative and
is positive, therefore the value of
changes its sign for
.
By the location principle
has a zero between
and

Observe the graph:
\The curve crosses the
-axis between
and
.
Therefore, the zeros of
on
occur between
and
