g(x)=3x+4
We can see that given function is linear. Therefore, it belongs to the family of linear functions, with a parent function of y=x.
Domain
Unless specific restrictions are given, the domain of linear functions is usually all real numbers.
Domain:& - ∞ < x < ∞
Range
Unless specific restrictions are given, the range of linear functions is also all real numbers.
Range:& - ∞ < x < ∞
Checking the Answer
To verify your answer, enter the function rule in the calculator by pushing Y= and writing the function rule in the first row. Next, by pushing GRAPH, the calculator will draw the graph of the function.
Looking at the graph, we can confirm that our solution is correct.
