What is the domain of the function in the graph?
A. 4≤y≤6
B. 20≤y≤70
C. 4≤x≤6
D. 20≤x≤70

Answer:
C. 4≤x≤6
Step-by-step explanation:
First things first, let’s learn the difference between domain and range. Domain is the spread of the x values and range is the spread of the y values. This means that in this question, you can rule out options A and B because those could potentially show range. Now we are left with options C and D. When we look at the first x coordinate, we see that it’s a 4. The last x coordinate is a 6. This means that the domain is greater than or equal to 4, but less than or equal to 6. You can also represent it as 4≤x≤6.
Hope that helps! Have a fantastic day!
