Help with brothers math homework?I can't help because I forgot how to do this

See below.

Step-by-step explanation:

The range of a graph is the span of y-coordinates the graph covers.

From the graph, we can see that the graph covers all y-values between the values of y=-8 and y=7.

Therefore, the range is all of the numbers in between them including them.

In interval notation, this is:

We use brackets instead of parentheses because we include the numbers.

And in set notation, this is:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
