What is the Domain and Range?

Domain = (-∞, ∞) Range = (-∞, ∞) Step-by-step 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|x∈R}The range is the set of all valid yvalues. Use the graph to find the range.Interval Notation:(−∞,∞)Set-Builder Notation:{y|y∈R}Determine the domain and range.Domain: (−∞,∞),{x|x∈R}Range: (−∞,∞),{y|y∈R}image of graph

Ithink it is b and d
