Gretta has 40 raffle tickets to sell. she is required to sell at least 15 tickets. she sells the raffle tickets for $10 each.
the amount of money gretta makes from selling x raffle tickets is represented by a function.
f(x)=10x
what is the practical range of the function?
a. all integers from 15 to 40, inclusive.
b. all multiples of 10 between 0 and 400, inclusive.
c. all real numbers.
d. all multiples of 10 between 150 and 400, inclusive.

(D) All multiples of 10 between 150 and 400, inclusive. i took the test myself.

Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.

Step-by-step explanation:

We have been given the information that gretta is selling x raffle ticket by a function

f(x)=10 x

Range is the values that y takes in a particular function

Here, we will get any value which is multiple of 10 since we have a function 10 times of something whatever value we put for x we will get multiple of 10.

Hence, Option d is correct that is range of the function is all multiples of 10 between 150 and 400, inclusive.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
