The LNHS Lions stadium seats about 2,000 people. The tickets sell for $6 each. The function f(x) = 6x represents the situation where x is the number of people in attendance and f(x) is the amount of money LNHS makes as revenue.

What is the range of the situation?

• 0 < f(x) < 6

• 0 < f(x) < 2,000

• 0 < f(x) < 12,000

• 2,000 < f(x) < 12,000

Pedro is driving to Nevada. The distance d he has left to travel, based on the hours driving h, can be modeled by the function:

d(h) = 2100 - 70h

What does the 2100 tell you?

• the range maximum; it's how fast Pedro is going to drive

• the range maximum; it's how far Pedro is from Nevada at the start

• part of the domain; it's how many hours it will take to get to Nevada

• part of the domain; it's how far Pedro is from Nevada at the start

Pedro is driving to Nevada. The distance d he has left to travel, based on the hours driving h, can be modeled by the function:

d(h) = 2100 - 70h

What kind of numbers can you use for the range here?

• all positive numbers; the miles just have to be ANY positive number

• all real numbers; the miles can literally be anything, including decimals

• the range, which is measuring miles, can be any positive real number (including decimals) up to 2100. The function stops at 2100 miles since he reaches Nevada.

A Water tank is draining and takes a certain amount of time. Which inequality best represents the domain?

• 0 < y < 500

• 500

• 0 < x < 20

• 20

• HINT: What is the smallest x and what is the biggest?

A student rode a bike from school to a recreation center. The graph shows the student's distance in miles from the recreation center after riding the bike for x minutes. What is the range of the function for this situation? HINT: what are the smallest and biggest y values the line touches?

• All real numbers greater than or equal to 0 and less than or equal to 28.

• All real numbers greater than or equal to 0 and less than or equal to 9.

• All real numbers less than or equal to 28.

• All real numbers less than or equal to 9.
