Suppose
that
we
are
finding
the
domain
of
a
function,
and
we
find
that
the
domain
is
all
numbers
that
are
at
least
—2
but
less
than
&
.
Which
of
the
following
intervals
would
we
write
as
our
domain?

Inequality
notation
can
use
either
square
brackets
@,
b|
or
round
brackets
(a,b)
.
Square
brackets
mean
that
the
a
value
is
included
in
the
interval,
while
round
brackets
mean
@
is
excluded.
Since
the
question
states
at
least
—2
,
that
means
it
includes
—2
.
So,
you
would
use
square
brackets.
The
phrase
less
than
§
does
not
include
8
,
so
you
would
use
round
brackets.
Therefore,
your
answer
should
be
[—2,
8)
.

PART
1.
To
convert
a
fraction
to
a
percent,
we
divide
the
numerator
by
the
denominator
and
multiply
by
100,
so
m
becomes
5
as
a
percent.
