Graph the function defined by f(x) = (x+21)

Answer:
A
Step-by-step explanation:
Consider the parent function [tex]y=|x|.[/tex] The graph of this function is represented as red graph in attached diagram.
Now consider the function [tex]y=|x+2|.[/tex]
Remind main translations of the graph of the function [tex]y=f(x):[/tex]
In your case, the graph of the function [tex]y=|x+2|[/tex] is translated graph of the function [tex]y=|x|[/tex] 2 units to the left (blue graph). So, correct answer is option A.
