What are the domain and range of the real-valued function f(x) = – 3+ V4x12?Need help with this practice question

Solution:
The domain of a function f(x) is the set of all input values for which the function is real and defined.
The range of the function is the set of all values that f(x) takes. This means the set of values the dependent variable takes for which the function is defined.
Given:
[tex]f(x)=-3+\sqrt[]{4x-12}[/tex]
