Answer:
The domain is all real numbers such that -6≤x≤-2, and the range is all real numbers greater than or equal to -4.
Step-by-step explanation:
The domain refers to the set of possible <u>input</u> values, so in the domain of a graph consists of all the input values shown on the x-axis, in this case, all numbers beetwen -6 and -2.
