Question

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.

Answer 1

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

Answer 2

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

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.
