1. 24

2. 0

3. a [4.9] and [3.1]      and      c [-6] and [-6]

4. edge The statement is not true for all real numbers. It is only true for decimal or fractional values of x . If x is an integer, then the ceiling function returns x when the input is x . But, the flooring function returns x + 1 when the input is x + 1. Since x does not equal x + 1 when x is an integer, the expressions are not equal when x is an integer.

5. edge There are three steps. The steps are at 8 from 0 to 1, at 12 from 1 to 2, and at 16 from 2 to 3. Closed circles are on the left side of each step, and open circles are on the right.

6. all real numbers

7. all multiples of 4

8. multiples of 8 greater than 0

9. 3

10. real numbers ≥ 0

11. integers ≥ 0

12. f(x)=2.50[x-1]

here's your reminder to fix your posture (you know you're slouching, that'll hurt your back when you're old lol) and go get some water! hydration is best because your body uses it to regulate body temperature, keep joints lubricated, prevent infections, deliver nutrients to cells, and keep organs functioning properly. being well-hydrated also improves sleep quality, cognition, and mood! also, if you don't drink water for 3-21 days (depends on age and body and stuff) you'll die. so there's that too.

summary of that ^ fix your posture and drink some water <3
