Me pls
a vendor has 30 umbrellas to sell. he sells them for $20 each. the function m(u) = 20u models the total amount of money the vendor makes from selling u umbrellas. what are the practical domain and range of the function?

Domain={0,30},Range={0,600}

Step-by-step explanation:

Total umbrellas=30

Price of each umbrella=$20

m(u)=20u

where

u is number of umbrellas

m(u) total amount vendor makes by selling u number of umbrellas

So Practically,The extreme cases are

So Domain is {0,total number of umbrellas}={0,30}

Putting this extreme value of domains as u in function m(u),

we get the range of m(u)={0$20,30$20}

⇒ Range={0,$600}

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
