Let the graph of f(x) represent the cost in thousands of dollars to feed the zoo animals daily, where x is the number of animals measured in hundreds. What does the solution to the function (2, 7) represent?

a graph of a function that decreases from the upper left, travels through an ordered pair labelled, 2, 7, and then increases toward the right

There are 200 animals, and the cost is $7,000 daily.
There are 2,000 animals, and the cost is $700 daily.
There are 700 animals, and the cost is $2,000 daily.
There are 7,000 animals, and the cost is $200 daily.

There are 200 animals, and the cost is $7,000 daily.

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?

f(150) represents the average number of days houses stay on the market before being sold for $150,000.
Houses sell on the market for an average of $150,000 and stay on the market an average of 150 days before being sold.
Houses sell for an average of $150,000.
f(150) indicates houses stay on the market an average of 150 days before being sold.

f(150) represents the average number of days houses stay on the market before being sold for $150,000.

If g(x) = x2 + 2, find g(3).

g(3) = 32 + 2 = 11

If g(x) = x2 + 2, find g(3).

9
8
11
6

g(3) = 32 + 2 = 11. Therefore, the correct answer is 11.

Jamie rents a movie for a flat fee of $2.50 plus an additional $0.75 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Jamie has the movie.

c(x) = 2.50x + 1.25
c(x) = 3.25
c(x) = 2.50 + 0.75x
c(x) = (2.50 + 0.75)x

c(x) = 2.50 + 0.75x

For the function f(x) = x + 5, what is the ordered pair for the point on the graph where x = 4w?

(4w, x + 5)
(4w, 4w + 5)
(x, x + 5)
(x, 4w + 5)
