Using the given graphs, let's find the domain and the range of each function.
• The domain is the set of all possible values of x contained in the graph.
,
• The range is the set of all possible values of y contained in the graph.
We have the following:
• Graph 1:
Domain: We can see the line starts with a closed dot on x = 0 and ends with a closed dot on x = 18.
Therefore, the domain will be all numbers from 0 to 18.
Hence, the domain is:
0 ≤ x ≤ 18
Range: The line goes from y =200 to y = 2000
Therefore, the range is:
Range: 200 ≤ y ≤ 2000
• Graph 2:
Domain: The line starts from x = 0 to x = 4
The domain is:
0 < x < 4
Range: Here, the range will be:
0 < y < 160
ANSWER:
• Graph 1:
Domain: {0 ≤ x ≤ 18}
Range: {200 ≤ y ≤ 2000}
• Graph 2
Domain: {0 < x < 4}
Range: {0 < y < 160}
