What you can say about the function using its rule?
Function Family: Absolute Value
Domain: All real numbers
Range: y≥2
We want to find out a few pieces of information about the given function.
Let's answer these questions!
We can see that given function is an absolute value. Therefore, it belongs to the family of absolute value functions, with a parent function of y=|x|.
Unless specific restrictions are given, the domain of absolute value functions is usually all real numbers. Domain:& - ∞ < x < ∞
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.
