B. {(15,0),(15,-2)}
Function?
Domain:
Range

Answers:

Explanation:

The domain consists of the set of x coordinates of each point. In this case, we only have one x value listed. The domain is {15}. Use curly braces even if there's only one item. This tells the reader we have a set.

The range is {0,-2} to indicate the y coordinates of the two points.

We don't have a function because x = 15 repeats itself. The input x = 15 leads to multiple outputs at the same time, which isn't allowed if you want a function. You can use the vertical line test as a visual way to see that we don't have a function.

the answer to the expression is 83

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
