Identify the Domain and Range of a Function from Its $( - \infty , \infty )$

Identify the Domain and Range of a Function from Its Graph
Use the graph to determine the function's domain and range.
-

A) domain: $( - \infty , \infty )$
range: $( - \infty , 3 ]$
B) domain: $( - \infty , \infty )$
range: $( - \infty , \infty )$
C) domain: $( - \infty , 5 ]$
range: $( - \infty , 3 ]$
D) domain: $( - \infty , 5 )$ or $( 5 , \infty )$
range: $( - \infty , 3 )$ or $( 3 , \infty )$
