Answer:

The range here is the set {8, -10, -4, 20, 32}.

Step-by-step explanation:

Please use " ^ " to denote exponentiation. Thanks. f(x)=x^2 + 5x - 4

f(-4)=(-4)^2 + 5(-4) - 4 = 8

f(-2)=(-2)^2 + 5(-1) - 4 = -10

f(0)=0^2 + 5(0) - 4 = -4

f(3) =3^2 + 5(3) - 4 = 20

f(4)=4^2 + 5(4) - 4 = 32

In this problem we have to calculate the actual function values for the given domain (input values). The range here is the set {8, -10, -4, 20, 32}.

You would probably need a little larger sample of people because not all people wear corrective lenses. In almost any other survey, this would be a scientist’s dream, but in this one, you’d need it to be a little bigger.

Answer: The percent of the total was spent on veterinarian bills is 27.70% ( approx).

Step-by-step explanation:

Given, In 2011, Americans spent approximately $50.9 billion on their pets.

i.e. Total amount they spent on pets = $50.9 billion

Amount spent for veterinarian bills. = $14.1 billion was for veterinarian bills.

Then, the percent of the total was spent on veterinarian bills would be :

$\dfrac{\text{Amount spent for veterinarian bills. }}{\text{Total amount they spent on pets}}\times100\\\\=\dfrac{14.1}{50.9}\times100\\\\=27.7013752456\approx27.70\%$
