Question

Help please xx

Answer 1

The domain of the first function is (-infinity,infinity)

Answer 2

The domain is how far the on the graph the x goes goes.

Answer 3

As for the range, it basically asks how low it goes to how high it goes.

Answer 4

so it would be [3,8] . notice how I use brackets this time, this is because they are closed points so they are included in the answer. If they were open points, you would use These () like the first question. You use those in the first one because infinity is not a definitive number.

Answer 5

So for #12 it would be [3,8]

Answer 6

yes

Answer 7

#11 would be (∞,-∞)
