For the linear function ƒ(x) = 7x – 4, find the range of ƒ(x) at x = –2, 0, and 2. Question 19 options: A) ƒ(–2) = 10, ƒ(0) = –4, ƒ(2) = –18 B) ƒ(–2) = –18, ƒ(0) = –4, ƒ(2) = 10 C) ƒ(–2) = 18, ƒ(0) = –4, ƒ(2) = 10 D) ƒ(–2) = –18, ƒ(0) = 4, ƒ(2) = 10

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
