Step-by-step explanation:
Domain:
(
−
∞
,
+
∞
)
Range:
(
−
∞
,
+
∞
)
Explanation:
Your function has no restrictions for its domain, since it's defined for all
x
∈
R
.
Its domain will thus be
(
−
∞
,
+
∞
)
.
The same can be said for its range. Your function can take any avalue of
x
and produce any value of
y
∈
R
, so its range will be
(
−
∞
,
+
∞
)
.
