Domain restrictions are what x values make the denominator zero.
a² + 5a - 36 = (a + 9)(a - 4)
a ≠ -9 ; a ≠ 4
For between
and
, we have
when
;
for
; and
for
is continuous over its domain, so the intermediate value theorem tells us that
is true for .
For all , we take into account that
is
-periodic, so the above inequality can be expanded to
where is any integer. Equivalently,
To get the corresponding solution set for
simply replace with
