Answer:
The first table is a function.
Domain for the first graph: {1, 5, 10, 11, 14}
Range for the first graph: {6, 50, 150, 176, 266}
The second table is a function
Domain for the second graph: {0, 10, 20, 30, 40}
Range for the second graph: {0, 300, 600, 900, 1200}
Step-by-step explanation:
To tell whether if a relation is a function is to determine if the x values repeat itself. If the x value repeats itself, it is not a function. If it doesn't repeat itself, it is therefore a function. You can also tell if a relation is a function by doing the vertical line test. Draw a vertical line on a graph and if it hits more than one point, the relation is not a function. The domain are the x values while the range are the y values. When you're plotting the domain/range, make sure to put the numbers in order from least to greatest, use curly brackets instead of parentheses, and don't repeat the same numbers. So yeah a brainliest would be great but you don't have too.
