Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

Answer:
14/4 or 7/2
Step-by-step explanation:
6 - (-7)
---------
-3 - (-7)
When you subtract a - its really just adding
2X + (2X+10)= 34
Width is 6, Length is 11
6 x 11 is 66
Area is 66
I’m pretty sure $1,800 Because if you subtract 660 by 470 you get 190 and it you multiply 190 by 6 years you get 1140 and if you add 1140 and 660 you get 1,800
X is 5 in this case!!!!hope it helps
