[25 POINTS] determine whether each relation is a function. If so, provide the domain and range.​

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.

step-by-step explanation: yes

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
