HELP I DONT UNDERSTAND PLSS HELP :(

D

Step-by-step explanation:

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

From the graph, we can see that the span of y-values covered goes from y=-3 all the way to y=3.

However, note that at y=-3, while it is a closed circle, it is an open circle at y=3.

This means that we do not include y=3 in our range, but we do include y=-3 in our range.

So, our range is all values between -3 and 3 including -3.

In set notation, this is (and remember since this is the range, to use y):

So, our answer is D.

And we're done!

the two may have that, even a breakdown is probably offered

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
