Question

What is the Domain and Range?

Answer 1

Domain = (-∞, ∞) Range = (-∞, ∞)

Explanation:

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:

(−∞,∞)

Set-Builder Notation:

x

The range is the set of all valid y

values. Use the graph to find the range.

Interval Notation:

(−∞,∞)

Set-Builder Notation:

y∈R

Determine the domain and range.

Domain: (−∞,∞),x∈R

Range: (−∞,∞),y
