Okay so basically domain =input and range =output. you can never have a negative number underneath the square root sign because it will make the answer imaginary (i), unless you are on that concept. Therefore the range is any number greater than 0. -> all real numbers greater than or = 0
for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.

Answer:
p = -0.002n +145
Step-by-step explanation:
You are given two points: (n, p) = (46000, 53) and (50000, 45). The 2-point form of the equation of a line is useful for this.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
p = (45 -53)/(50000 -46000)(n -46000) +53
p = -8/4000(n -46000) +53
p = -0.002n +145 . . . . . demand equation
Hm i think it might be 2:8?
