The answer is all real numbers greater than or equal to -3, as domain and range.
What is the domain and range of function?
A function's domain and range are its components. A function's range is its potential output; its domain is the set of all conceivable input values. Domain, Function, and Range. If a function f: A B exists that maps every element in A to an element in B, then A is the domain and B is the co-domain. The image of an element 'a' under a relation R is provided by 'b,' where (a,b) R. The set of photographs makes up the function's range.
The domain of a relation or a function is the set of all possible values for an input in that relation/function.
The range of a relation or function is the set of all possible values that can be the result of a relation or function.
From the graph, nothing can be seen on the left side of x = - 3 and the graph is continuous and going in the direction of infinity on the right side of the x axis.
Hence all real numbers greater than or equal to -3
