Step-by-step explanation:

We are given the following information in the question:

A table is shown showing trees on two different plots of land which are tested for disease.

    Tree:        1           2           3           4          5           6          7

Disease:        Y          N           Y           Y          Y          N         N

We have to find:

Calculating from the table, we can fill the values as:

                                             Plot A                Plot B

Disease Present                        1                          3

Here is a table of values y=f(x).
Mariulka [41]

A. <u>False.</u> The range of f(x) is the set of values it can produce. In the table, f(x) produces values from 0 to 3. However, the range of all real numbers is all rational numbers, basically from -\infty to \infty, not just a few numbers in-between. So, the range of f(x) is not all real numbers.

B.  <u>True.</u> Looking at the table, when x=-3, f(x)=2. This is another way of saying that f(-3)=2, which is what B is saying.

C. <u>True.</u> The domain of f(x) is the set of values of x that produce some output in f(x). Looking at the table, all of the x values listed on it are in the set \{-5, -3, 0, 2, 6, 7, 9, 10, 13\}, which is what C is saying.

D. <u>False.</u> Looking at the table, when x=0, f(x)=3. This is another way of saying that f(0)=3, which is <em>not </em>what B is saying.
