Answer:
1st function: all negative real numbers
2nd function: all real numbers
3rd function: all real numbers except -3 ≤ x ≤ 3
4th function: all real numbers between -3 and 3
Step-by-step explanation:
In the picture attached, the question is shown.
The domain is the set of all the numbers that the independent variable (here, x) can assume.
In this exercise we have to identify which types of graph correspond and correlate them with the given sentences, in this way we find that:
1)all negative real numbers
2) all real numbers
3) all real numbers except -3 ≤ x ≤ 3
4) all real numbers between -3 and 3
So then when we deal with graph it is important to observe its axes then:
1) In the first case we have to be all negative and real numbers since it is only found in this part of the graph.
2) The second graph reports all the real numbers, that is, the numbers that are in the positive part and in the negative part.
3) The third case is very similar to the second, where we find all the real numbers, but the graph "skips" the numbers 3 and -3.
4) Finally, the last graph is just between the values of 3 and -3 with a line delimiting these values.
